Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Auth Bypass: Inconsistent padding of 32-byte role identifiers (left-padding instead of right-padding) led to validation failures, resulting in authorization and permission-check bypasses across the EVM.
Denial of Service: Unbounded stack memory allocation during EVM execution allowed out-of-memory panics, exposing the validators to targeted crash-based denial of service.
Auth Bypass: Unset public keys could bypass strict signature verification validation on CurveTypeUnset, allowing unauthorized transaction execution.
