Summary

LACK EIP 1967

Vulnerability Details

Storage collision because of lack of EIP1967 could cause conflicts and override sensible variables.
This vulnerability refers to the potential for storage collision between the Proxy contract and its Implementation contract. In the provided code, the Proxy contract uses the first storage slot to store the address of the Implementation contract. If the Implementation contract also uses its first storage slot for storage, it could overwrite the address of the Implementation contract in the Proxy contract, leading to unexpected behavior. This vulnerability could be mitigated by following EIP 1967, which recommends storing the address of the Implementation contract at a specific storage slot to avoid potential collisions.
