Vulnerability details

Every Solidity file specifies in the header a version number of the format pragma solidity ^0.8.0. The caret (^) before the version number implies an unlocked pragma, meaning that the compiler will use the specified version or above.

It’s usually a good idea to pin a specific version to know what compiler bug fixes and optimizations were enabled at the time of compiling the contract.

Impact

Recommended mitigation steps

Pin the compiler versions.
