Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Memory Corruption: Multiple fixes address unsafe assembly memory offset calculations, dirty bits in recipient/path decoding, and missing bounds checks, indicating a systemic risk in hand-written Yul that can corrupt state or lead to fund loss.
Access Control: Proxy upgrade and deployment paths have repeatedly allowed reinitialization, version skipping, unauthorized unlock, and authorization bypass, posing privilege-escalation and governance-control risks.
Signature Validation: Multiple signature-verification bypasses were fixed across factories and settlement modules, including incorrect comparison operators, ABI encoding errors, and missing txOrigin validation, enabling unauthorized token transfers or order interception.
