Recurring patterns

The bug types that recur here, drawn from past fixes, not open vulnerabilities.

Auth Bypass: Smart contracts could call the proxy precompile or bypass validation to execute unauthorized proxy transactions, bypassing EVM account code limits and escalating privileges.

Auth Bypass: Lack of ownership verification during author key mapping allowed users to overwrite, overwrite-delete, or take over other users' registered author associations.

Integer Overflow: Silent truncation and inadequate bounds checks during the decoding of EVM precompile inputs allowed unsafe deserialization of Solidity uint types.
