Highlights
Auth Bypass: 28 prior fixes. Scrutinize any change in this area.
packages/protocol/contracts/governance/Validators.sol: most-fixed (5 issues). Treat as high-risk during review.
46 high-severity fixes in this history; regressions here are high-impact.
Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Auth Bypass: Uninitialized template implementations behind proxies allow malicious actors to initialize and take over or self-destruct implementation contracts. Subsequent fixes introduced InitializableV2 to automatically initialize logic contracts in constructors.
Arbitrary Code Execution: Performing delegatecall on non-contract addresses within proxy and multisig components can lead to silent failures or arbitrary execution. Restricting these targets requires checking code size with extcodesize.
Cryptographic Weakness: Validator registration could bypass proof-of-possession checks or allow replay attacks if the signature was not strongly bound to the sender's Ethereum address.
