All contracts in scope use a vulnerable Solidity version.
For all contracts in scope, an outdated Solidity version, 0.7.6, is currently in use. However, at the time of writing, there are 9 known bugs in version 0.7.6.
This can introduce vulnerabilities to the project that were fixed in newer solidity versions, such as the Head Overflow Bug in Calldata Tuple ABI-Reencoding.
Manual review.
Consider upgrading the codebase to use a version of Solidity that does not contain known bugs, e.g., 0.8.23.
