Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Auth Bypass: Mint function lacked access control, allowing unauthorized state manipulation; fixed by adding onlyCustomToken modifier and migration tracking.
Auth Bypass: Zero-address minting was allowed to any caller, enabling unauthorized token creation; now restricted to bridge sender.
