Vulnerability details

Impact

If there are no hooks to process, the current code does not explicitly handle this scenario. Without a revert , the condition might not be working as intended.

Proof of Concept

there is apotential issue in the stopRent function of the stop.sol contract. In the specific section where hooks are processed: https://github.com/re-nft/smart-contracts/blob/3ddd32455a849c3c6dc3c3aad7a33a6c9b44c291/src/policies/Stop.sol#L348C1-L348C1

if (order.hooks.length > 0) { _removeHooks(order.hooks, order.items, order.rentalWallet); } It appears that there is no revert parameter if the logic order.hooks.length is equal to or less than 0. This means the function might proceed without handling this case.

Tools Used

Recommended Mitigation Steps

Add revert param after if
