Vulnerability details

Impact

The contracts use the latest Solidity compiler version 0.8.7 released in August. While this version supports the London upgrade among other optimizations and internal bug fixes, using the latest solc version may also be susceptible to undiscovered bugs that may be discovered and fixed in a few months.

Proof of Concept

Manual Analysis

Recommended Mitigation Steps

Consider using a few releases older e.g. 0.8.4 which has been around for a few more months and so a bit more time-tested.
