Recurring patterns

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

Auth Bypass: Critical signature authorization bypasses occurred during token approvals by incorrectly mapping the recovered 'owner' parameter and utilizing insecure fallback eth_sign signature recovery paths. Developers must enforce strict EIP-712 compliant recovery without fallback mechanisms.

Signature Malleability: The use of malleable or raw ERC-191 signatures permitted potential cross-contract replay attacks, requiring a migration to structured EIP-712 domain-separated hashing.

Unchecked Return Value: Incompatible ERC20 transfer failures could silent-fail and bypass execution reverts if return values were not explicitly verified inside the safeTransfer wrapper.
