First Flight #21: KittyFi

Summary

The purrrCollateralToAave and purrrCollateralFromAave functions lack a more robust authorization mechanism to ensure that only authorized entities can perform these critical operations.

Vulnerability Details

• Location: purrrCollateralToAave and purrrCollateralFromAave functions.

• Description: The contract uses a simple ownership check (onlyMeowntainer) for managing critical operations like supplying and withdrawing collateral to and from Aave. This can be restrictive and might require more flexibility and security.

Impact

• Severity: Medium

• Effect: The lack of a more granular authorization mechanism can lead to difficulties in managing the contract and could become a security risk if the meowntainer compromise occurs.

Recommendations

Implement a more flexible and granular authorization system, such as a multi-signature wallet or a role-based access control mechanism.
