CVE-2024-27094

Impact

The Base64.encode function encodes a bytes input by iterating over it in chunks of 3 bytes. When this input is not a multiple of 3, the last iteration may read parts of the memory that are beyond the input buffer.

Although the encode function pads the output for these cases, up to 4 bits of data are kept between the encoding and padding, corrupting the output if these bits were dirty (i.e. memory after the input is not 0). These conditions are more frequent in the following scenarios:

A bytes memory struct is allocated just after the input and the first bytes of it are non-zero.
The memory pointer is set to a non-empty memory location before allocating the input.

Developers should evaluate whether the extra bits can be maliciously manipulated by an attacker.

Patches

Upgrade to 5.0.2 or 4.9.6.

([#4063](https://redirect.github.com/OpenZeppelin/openzeppelin-contracts/pull/4063)) - `MerkleProof`: optimize by using unchecked arithmetic. ([#3745](https://redirect.github.com/OpenZeppelin/openzeppelin-contracts/pull/3745)) ##### Breaking changes - `EIP712`: Addition of ERC5267 support requires support for user defined value types, which was released in Solidity version 0.8.8. This requires a pragma change from `^0.8.0` to `^0.8.8`. - `EIP712`: Optimization of the cache for the upgradeable version affects the way `name` and `version` are set. This is no longer done through an initializer, and is instead part of the implementation's constructor. As a consequence, all proxies using the same implementation will necessarily share the same `name` and `version`. Additionally, an implementation upgrade risks changing the EIP712 domain unless the same `name` and `version` are used when deploying the new implementation contract. ##### Deprecations - `ERC20Permit`: Added the file `IERC20Permit.sol` and `ERC20Permit.sol` and deprecated `draft-IERC20Permit.sol` and `draft-ERC20Permit.sol` since [EIP-2612](https://eips.ethereum.org/EIPS/eip-2612) is no longer a Draft. Developers are encouraged to update their imports. ([#3793](https://redirect.github.com/OpenZeppelin/openzeppelin-contracts/pull/3793)) - `Timers`: The `Timers` library is now deprecated and will be removed in the next major release. ([#4062](https://redirect.github.com/OpenZeppelin/openzeppelin-contracts/pull/4062)) - `ERC777`: The `ERC777` token standard is no longer supported by OpenZeppelin. Our implementation is now deprecated and will be removed in the next major release. The corresponding standard interfaces remain available. ([#4066](https://redirect.github.com/OpenZeppelin/openzeppelin-contracts/pull/4066)) - `ERC1820Implementer`: The `ERC1820` pseudo-introspection mechanism is no longer supported by OpenZeppelin. Our implementation is now deprecated and will be removed in the next major release. The corresponding standard interfaces remain available. ([#4066](https://redirect.github.com/OpenZeppelin/openzeppelin-contracts/pull/4066)) ### [`v4.8.3`](https://redirect.github.com/OpenZeppelin/openzeppelin-contracts/blob/HEAD/CHANGELOG.md#483-2023-04-13) [Compare Source](https://redirect.github.com/OpenZeppelin/openzeppelin-contracts/compare/v4.8.2...v4.8.3) - `GovernorCompatibilityBravo`: Fix encoding of proposal data when signatures are missing. - `TransparentUpgradeableProxy`: Fix transparency in case of selector clash with non-decodable calldata or payable mutability. ([#4154](https://redirect.github.com/OpenZeppelin/openzeppelin-contracts/pull/4154)) ### [`v4.8.2`](https://redirect.github.com/OpenZeppelin/openzeppelin-contracts/blob/HEAD/CHANGELOG.md#482-2023-03-02) [Compare Source](https://redirect.github.com/OpenZeppelin/openzeppelin-contracts/compare/v4.8.1...v4.8.2) - `ERC721Consecutive`: Fixed a bug when `_mintConsecutive` is used for batches of size 1 that could lead to balance overflow. Refer to the breaking changes section in the changelog for a note on the behavior of `ERC721._beforeTokenTransfer`. ##### Breaking changes - `ERC721`: The internal function `_beforeTokenTransfer` no longer updates balances, which it previously did when `batchSize` was greater than 1. This change has no consequence unless a custom ERC721 extension is explicitly invoking `_beforeTokenTransfer`. Balance updates in extensions must now be done explicitly using `__unsafe_increaseBalance`, with a name that indicates that there is an invariant that has to be manually verified. ### [`v4.8.1`](https://redirect.github.com/OpenZeppelin/openzeppelin-contracts/blob/HEAD/CHANGELOG.md#481-2023-01-12) [Compare Source](https://redirect.github.com/OpenZeppelin/openzeppelin-contracts/compare/v4.8.0...v4.8.1) - `ERC4626`: Use staticcall instead of call when fetching underlying ERC-20 decimals. ([#3943](https://redirect.github.com/OpenZeppelin/openzeppelin-contracts/pull/3943)) ### [`v4.8.0`](https://redirect.github.com/OpenZeppelin/openzeppelin-contracts/blob/HEAD/CHANGELOG.md#480-2022-11-08) [Compare Source](https://redirect.github.com/OpenZeppelin/openzeppelin-contracts/compare/v4.7.3...v4.8.0) - `TimelockController`: Added a new `admin` constructor parameter that is assigned the admin role instead of the deployer account.

([#3506](https://redirect.github.com/OpenZeppelin/openzeppelin-contracts/pull/3506)) - `ERC20`: optimize `_transfer`, `_mint` and `_burn` by using `unchecked` arithmetic when possible. ([#3513](https://redirect.github.com/OpenZeppelin/openzeppelin-contracts/pull/3513)) - `ERC20Votes`, `ERC721Votes`: optimize `getPastVotes` for looking up recent checkpoints. ([#3673](https://redirect.github.com/OpenZeppelin/openzeppelin-contracts/pull/3673)) - `ERC20FlashMint`: add an internal `_flashFee` function for overriding. ([#3551](https://redirect.github.com/OpenZeppelin/openzeppelin-contracts/pull/3551)) - `ERC4626`: use the same `decimals()` as the underlying asset by default (if available). ([#3639](https://redirect.github.com/OpenZeppelin/openzeppelin-contracts/pull/3639)) - `ERC4626`: add internal `_initialConvertToShares` and `_initialConvertToAssets` functions to customize empty vaults behavior. ([#3639](https://redirect.github.com/OpenZeppelin/openzeppelin-contracts/pull/3639)) - `ERC721`: optimize transfers by making approval clearing implicit instead of emitting an event. ([#3481](https://redirect.github.com/OpenZeppelin/openzeppelin-contracts/pull/3481)) - `ERC721`: optimize burn by making approval clearing implicit instead of emitting an event. ([#3538](https://redirect.github.com/OpenZeppelin/openzeppelin-contracts/pull/3538)) - `ERC721`: Fix balance accounting when a custom `_beforeTokenTransfer` hook results in a transfer of the token under consideration. ([#3611](https://redirect.github.com/OpenZeppelin/openzeppelin-contracts/pull/3611)) - `ERC721`: use unchecked arithmetic for balance updates. ([#3524](https://redirect.github.com/OpenZeppelin/openzeppelin-contracts/pull/3524)) - `ERC721Consecutive`: Implementation of EIP-2309 that allows batch minting of ERC721 tokens during construction.

([#3565](https://redirect.github.com/OpenZeppelin/openzeppelin-contracts/pull/3565)) - `ECDSA`: Remove redundant check on the `v` value.

([#3580](https://redirect.github.com/OpenZeppelin/openzeppelin-contracts/pull/3580)) - `VestingWallet`: remove unused library `Math.sol`. ([#3605](https://redirect.github.com/OpenZeppelin/openzeppelin-contracts/pull/3605)) - `VestingWallet`: make constructor payable. ([#3665](https://redirect.github.com/OpenZeppelin/openzeppelin-contracts/pull/3665)) - `Create2`: optimize address computation by using assembly instead of `abi.encodePacked`. ([#3600](https://redirect.github.com/OpenZeppelin/openzeppelin-contracts/pull/3600)) - `Clones`: optimized the assembly to use only the scratch space during deployments, and optimized `predictDeterministicAddress` to use fewer operations. ([#3640](https://redirect.github.com/OpenZeppelin/openzeppelin-contracts/pull/3640)) - `Checkpoints`: Use procedural generation to support multiple key/value lengths. ([#3589](https://redirect.github.com/OpenZeppelin/openzeppelin-contracts/pull/3589)) - `Checkpoints`: Add new lookup mechanisms. ([#3589](https://redirect.github.com/OpenZeppelin/openzeppelin-contracts/pull/3589)) - `Arrays`: Add `unsafeAccess` functions that allow reading and writing to an element in a storage array bypassing Solidity's "out-of-bounds" check.

([#3573](https://redirect.github.com/OpenZeppelin/openzeppelin-contracts/pull/3573)) - `Ownable2Step`: extension of `Ownable` that makes the ownership transfers a two step process. ([#3620](https://redirect.github.com/OpenZeppelin/openzeppelin-contracts/pull/3620)) - `Math` and `SignedMath`: optimize function `max` by using `>` instead of `>=`. ([#3679](https://redirect.github.com/OpenZeppelin/openzeppelin-contracts/pull/3679)) - `Math`: Add `log2`, `log10` and `log256`. ([#3670](https://redirect.github.com/OpenZeppelin/openzeppelin-contracts/pull/3670)) - Arbitrum: Update the vendored arbitrum contracts to match the nitro upgrade. ([#3692](https://redirect.github.com/OpenZeppelin/openzeppelin-contracts/pull/3692)) ##### Breaking changes - `ERC721`: In order to add support for batch minting via `ERC721Consecutive` it was necessary to make a minor breaking change in the internal interface of `ERC721`. Namely, the hooks `_beforeTokenTransfer` and `_afterTokenTransfer` have one additional argument that may need to be added to overrides: ```diff function _beforeTokenTransfer( address from, address to, uint256 tokenId, + uint256 batchSize ) internal virtual override ``` - `ERC4626`: Conversion from shares to assets (and vice-versa) in an empty vault used to consider the possible mismatch between the underlying asset's and the vault's decimals. This initial conversion rate is now set to 1-to-1 irrespective of decimals, which are meant for usability purposes only. The vault now uses the assets decimals by default, so off-chain the numbers should appear the same. Developers overriding the vault decimals to a value that does not match the underlying asset may want to override the `_initialConvertToShares` and `_initialConvertToAssets` to replicate the previous behavior. - `TimelockController`: During deployment, the TimelockController used to grant the `TIMELOCK_ADMIN_ROLE` to the deployer and to the timelock itself. The deployer was then expected to renounce this role once configuration of the timelock is over. Failing to renounce that role allows the deployer to change the timelock permissions (but not to bypass the delay for any time-locked actions). The role is no longer given to the deployer by default. A new parameter `admin` can be set to a non-zero address to grant the admin role during construction (to the deployer or any other address). Just like previously, this admin role should be renounced after configuration. If this param is given `address(0)`, the role is not allocated and doesn't need to be revoked. In any case, the timelock itself continues to have this role. ##### Deprecations - `EIP712`: Added the file `EIP712.sol` and deprecated `draft-EIP712.sol` since the EIP is no longer a Draft. Developers are encouraged to update their imports. ([#3621](https://redirect.github.com/OpenZeppelin/openzeppelin-contracts/pull/3621)) ```diff -import "@openzeppelin/contracts/utils/cryptography/draft-EIP712.sol"; +import "@openzeppelin/contracts/utils/cryptography/EIP712.sol"; ``` - `ERC721Votes`: Added the file `ERC721Votes.sol` and deprecated `draft-ERC721Votes.sol` since it no longer depends on a Draft EIP (EIP-712). Developers are encouraged to update their imports. ([#3699](https://redirect.github.com/OpenZeppelin/openzeppelin-contracts/pull/3699)) ```diff -import "@openzeppelin/contracts/token/ERC721/extensions/draft-ERC721Votes.sol"; +import "@openzeppelin/contracts/token/ERC721/extensions/ERC721Votes.sol"; ``` ##### ERC-721 Compatibility Note ERC-721 integrators that interpret contract state from events should make sure that they implement the clearing of approval that is implicit in every transfer according to the EIP. Previous versions of OpenZeppelin Contracts emitted an explicit `Approval` event even though it was not required by the specification, and this is no longer the case. With the new `ERC721Consecutive` extension, the internal workings of `ERC721` are slightly changed. Custom extensions to ERC721 should be reviewed to ensure they remain correct. The internal functions that should be considered are `_ownerOf` (new), `_beforeTokenTransfer`, and `_afterTokenTransfer`. ##### ERC-4626 Upgrade Note Existing `ERC4626` contracts that are upgraded to 4.8 must initialize a new variable that holds the vault token decimals. The recommended way to do this is to use a [reinitializer]: [reinitializer]: https://docs.openzeppelin.com/contracts/4.x/api/proxy#Initializable-reinitializer-uint8- ```solidity function migrateToV48() public reinitializer(2) { __ERC4626_init(IERC20Upgradeable(asset())); } ``` ### [`v4.7.3`](https://redirect.github.com/OpenZeppelin/openzeppelin-contracts/blob/HEAD/CHANGELOG.md#473-2022-08-10) [Compare Source](https://redirect.github.com/OpenZeppelin/openzeppelin-contracts/compare/v4.7.2...v4.7.3) ##### Breaking changes - `ECDSA`: `recover(bytes32,bytes)` and `tryRecover(bytes32,bytes)` no longer accept compact signatures to prevent malleability. Compact signature support remains available using `recover(bytes32,bytes32,bytes32)` and `tryRecover(bytes32,bytes32,bytes32)`. ### [`v4.7.2`](https://redirect.github.com/OpenZeppelin/openzeppelin-contracts/blob/HEAD/CHANGELOG.md#472-2022-07-25) [Compare Source](https://redirect.github.com/OpenZeppelin/openzeppelin-contracts/compare/v4.7.1...v4.7.2) - `LibArbitrumL2`, `CrossChainEnabledArbitrumL2`: Fixed detection of cross-chain calls for EOAs.

([#3380](https://redirect.github.com/OpenZeppelin/openzeppelin-contracts/pull/3380)) - `ERC20FlashMint`: Add customizable flash fee receiver. ([#3327](https://redirect.github.com/OpenZeppelin/openzeppelin-contracts/pull/3327)) - `ERC4626`: add an extension of `ERC20` that implements the ERC4626 Tokenized Vault Standard. ([#3171](https://redirect.github.com/OpenZeppelin/openzeppelin-contracts/pull/3171)) - `SafeERC20`: add `safePermit` as mitigation against phantom permit functions. ([#3280](https://redirect.github.com/OpenZeppelin/openzeppelin-contracts/pull/3280)) - `Math`: add a `mulDiv` function that can round the result either up or down. ([#3171](https://redirect.github.com/OpenZeppelin/openzeppelin-contracts/pull/3171)) - `Math`: Add a `sqrt` function to compute square roots of integers, rounding either up or down. ([#3242](https://redirect.github.com/OpenZeppelin/openzeppelin-contracts/pull/3242)) - `Strings`: add a new overloaded function `toHexString` that converts an `address` with fixed length of 20 bytes to its not checksummed ASCII `string` hexadecimal representation. ([#3403](https://redirect.github.com/OpenZeppelin/openzeppelin-contracts/pull/3403)) - `EnumerableMap`: add new `UintToUintMap` map type. ([#3338](https://redirect.github.com/OpenZeppelin/openzeppelin-contracts/pull/3338)) - `EnumerableMap`: add new `Bytes32ToUintMap` map type. ([#3416](https://redirect.github.com/OpenZeppelin/openzeppelin-contracts/pull/3416)) - `SafeCast`: add support for many more types, using procedural code generation. ([#3245](https://redirect.github.com/OpenZeppelin/openzeppelin-contracts/pull/3245)) - `MerkleProof`: add `multiProofVerify` to prove multiple values are part of a Merkle tree. ([#3276](https://redirect.github.com/OpenZeppelin/openzeppelin-contracts/pull/3276)) - `MerkleProof`: add calldata versions of the functions to avoid copying input arrays to memory and save gas. ([#3200](https://redirect.github.com/OpenZeppelin/openzeppelin-contracts/pull/3200)) - `ERC721`, `ERC1155`: simplified revert reasons. ([#3254](https://redirect.github.com/OpenZeppelin/openzeppelin-contracts/pull/3254), ([#3438](https://redirect.github.com/OpenZeppelin/openzeppelin-contracts/pull/3438))) - `ERC721`: removed redundant require statement. ([#3434](https://redirect.github.com/OpenZeppelin/openzeppelin-contracts/pull/3434)) - `PaymentSplitter`: add `releasable` getters. ([#3350](https://redirect.github.com/OpenZeppelin/openzeppelin-contracts/pull/3350)) - `Initializable`: refactored implementation of modifiers for easier understanding. ([#3450](https://redirect.github.com/OpenZeppelin/openzeppelin-contracts/pull/3450)) - `Proxies`: remove runtime check of ERC1967 storage slots. ([#3455](https://redirect.github.com/OpenZeppelin/openzeppelin-contracts/pull/3455)) ##### Breaking changes - `Initializable`: functions decorated with the modifier `reinitializer(1)` may no longer invoke each other. ### [`v4.6.0`](https://redirect.github.com/OpenZeppelin/openzeppelin-contracts/blob/HEAD/CHANGELOG.md#460-2022-04-26) [Compare Source](https://redirect.github.com/OpenZeppelin/openzeppelin-contracts/compare/v4.5.0...v4.6.0) - `crosschain`: Add a new set of contracts for cross-chain applications. `CrossChainEnabled` is a base contract with instantiations for several chains and bridges, and `AccessControlCrossChain` is an extension of access control that allows cross-chain operation. ([#3183](https://redirect.github.com/OpenZeppelin/openzeppelin-contracts/pull/3183)) - `AccessControl`: add a virtual `_checkRole(bytes32)` function that can be overridden to alter the `onlyRole` modifier behavior. ([#3137](https://redirect.github.com/OpenZeppelin/openzeppelin-contracts/pull/3137)) - `EnumerableMap`: add new `AddressToUintMap` map type. ([#3150](https://redirect.github.com/OpenZeppelin/openzeppelin-contracts/pull/3150)) - `EnumerableMap`: add new `Bytes32ToBytes32Map` map type. ([#3192](https://redirect.github.com/OpenZeppelin/openzeppelin-contracts/pull/3192)) - `ERC20FlashMint`: support infinite allowance when paying back a flash loan. ([#3226](https://redirect.github.com/OpenZeppelin/openzeppelin-contracts/pull/3226)) - `ERC20Wrapper`: the `decimals()` function now tries to fetch the value from the underlying token instance. If that calls revert, then the default value is used. ([#3259](https://redirect.github.com/OpenZeppelin/openzeppelin-contracts/pull/3259)) - `draft-ERC20Permit`: replace `immutable` with `constant` for `_PERMIT_TYPEHASH` since the `keccak256` of string literals is treated specially and the hash is evaluated at compile time. ([#3196](https://redirect.github.com/OpenZeppelin/openzeppelin-contracts/pull/3196)) - `ERC1155`: Add a `_afterTokenTransfer` hook for improved extensibility. ([#3166](https://redirect.github.com/OpenZeppelin/openzeppelin-contracts/pull/3166)) - `ERC1155URIStorage`: add a new extension that implements a `_setURI` behavior similar to ERC721's `_setTokenURI`. ([#3210](https://redirect.github.com/OpenZeppelin/openzeppelin-contracts/pull/3210)) - `DoubleEndedQueue`: a new data structure that supports efficient push and pop to both front and back, useful for FIFO and LIFO queues. ([#3153](https://redirect.github.com/OpenZeppelin/openzeppelin-contracts/pull/3153)) - `Governor`: improved security of `onlyGovernance` modifier when using an external executor contract (e.g. a timelock) that can operate without necessarily going through the governance protocol. ([#3147](https://redirect.github.com/OpenZeppelin/openzeppelin-contracts/pull/3147)) - `Governor`: Add a way to parameterize votes. This can be used to implement voting systems such as fractionalized voting, ERC721 based voting, or any number of other systems. The `params` argument added to `_countVote` method, and included in the newly added `_getVotes` method, can be used by counting and voting modules respectively for such purposes. ([#3043](https://redirect.github.com/OpenZeppelin/openzeppelin-contracts/pull/3043)) - `Governor`: rewording of revert reason for consistency. ([#3275](https://redirect.github.com/OpenZeppelin/openzeppelin-contracts/pull/3275)) - `Governor`: fix an inconsistency in data locations that could lead to invalid bytecode being produced. ([#3295](https://redirect.github.com/OpenZeppelin/openzeppelin-contracts/pull/3295)) - `Governor`: Implement `IERC721Receiver` and `IERC1155Receiver` to improve token custody by governors. ([#3230](https://redirect.github.com/OpenZeppelin/openzeppelin-contracts/pull/3230)) - `TimelockController`: Implement `IERC721Receiver` and `IERC1155Receiver` to improve token custody by timelocks. ([#3230](https://redirect.github.com/OpenZeppelin/openzeppelin-contracts/pull/3230)) - `TimelockController`: Add a separate canceller role for the ability to cancel. ([#3165](https://redirect.github.com/OpenZeppelin/openzeppelin-contracts/pull/3165)) - `Initializable`: add a reinitializer modifier that enables the initialization of new modules, added to already initialized contracts through upgradeability. ([#3232](https://redirect.github.com/OpenZeppelin/openzeppelin-contracts/pull/3232)) - `Initializable`: add an Initialized event that tracks initialized version numbers. ([#3294](https://redirect.github.com/OpenZeppelin/openzeppelin-contracts/pull/3294)) - `ERC2981`: make `royaltyInfo` public to allow super call in overrides. ([#3305](https://redirect.github.com/OpenZeppelin/openzeppelin-contracts/pull/3305)) ##### Upgradeability notice - `TimelockController`: **(Action needed)** The upgrade from <4.6 to >=4.6 introduces a new `CANCELLER_ROLE` that requires set up to be assignable. After the upgrade, only addresses with this role will have the ability to cancel. Proposers will no longer be able to cancel. Assigning cancellers can be done by an admin (including the timelock itself) once the role admin is set up. To do this, we recommend upgrading to the `TimelockControllerWith46MigrationUpgradeable` contract and then calling the `migrateTo46` function. ##### Breaking changes - `Governor`: Adds internal virtual `_getVotes` method that must be implemented; this is a breaking change for existing concrete extensions to `Governor`. To fix this on an existing voting module extension, rename `getVotes` to `_getVotes` and add a `bytes memory` argument. ([#3043](https://redirect.github.com/OpenZeppelin/openzeppelin-contracts/pull/3043)) - `Governor`: Adds `params` parameter to internal virtual `_countVote` method; this is a breaking change for existing concrete extensions to `Governor`. To fix this on an existing counting module extension, add a `bytes memory` argument to `_countVote`. ([#3043](https://redirect.github.com/OpenZeppelin/openzeppelin-contracts/pull/3043)) - `Governor`: Does not emit `VoteCast` event when params data is non-empty; instead emits `VoteCastWithParams` event. To fix this on an integration that consumes the `VoteCast` event, also fetch/monitor `VoteCastWithParams` events. ([#3043](https://redirect.github.com/OpenZeppelin/openzeppelin-contracts/pull/3043)) - `Votes`: The internal virtual function `_getVotingUnits` was made `view` (which was accidentally missing). Any overrides should now be updated so they are `view` as well.

🪧 Tips

### Chat There are 3 ways to chat with [CodeRabbit](https://coderabbit.ai): - Review comments: Directly reply to a review comment made by CodeRabbit. Example: - `I pushed a fix in commit , please review it.` - `Generate unit testing code for this file.` - `Open a follow-up GitHub issue for this discussion.` - Files and specific lines of code (under the "Files changed" tab): Tag `@coderabbitai` in a new review comment at the desired location with your query. Examples: - `@coderabbitai generate unit testing code for this file.` - `@coderabbitai modularize this function.` - PR comments: Tag `@coderabbitai` in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples: - `@coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.` - `@coderabbitai read src/utils.ts and generate unit testing code.` - `@coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.` - `@coderabbitai help me debug CodeRabbit configuration file.` Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments. ### CodeRabbit Commands (Invoked using PR comments) - `@coderabbitai pause` to pause the reviews on a PR. - `@coderabbitai resume` to resume the paused reviews. - `@coderabbitai review` to trigger an incremental review. This is useful when automatic reviews are disabled for the repository. - `@coderabbitai full review` to do a full review from scratch and review all the files again. - `@coderabbitai summary` to regenerate the summary of the PR. - `@coderabbitai resolve` resolve all the CodeRabbit review comments. - `@coderabbitai configuration` to show the current CodeRabbit configuration for the repository. - `@coderabbitai help` to get help. ### Other keywords and placeholders - Add `@coderabbitai ignore` anywhere in the PR description to prevent this PR from being reviewed. - Add `@coderabbitai summary` to generate the high-level summary at a specific location in the PR description. - Add `@coderabbitai` anywhere in the PR title to generate the title automatically. ### Documentation and Community - Visit our [Documentation](https://coderabbit.ai/docs) for detailed information on how to use CodeRabbit. - Join our [Discord Community](http://discord.gg/coderabbit) to get help, request features, and share feedback. - Follow us on [X/Twitter](https://twitter.com/coderabbitai) for updates and announcements.
