Highlights
Denial of Service: 107 prior fixes. Scrutinize any change in this area.
beacon_node/beacon_chain: most-fixed (10 issues). Treat as high-risk during review.
96 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: A hardcoded debug override completely bypassed cryptographic signature verification for attestations, undermining the core security mechanism of the consensus layer.
Cryptographic Signature Verification Bypass: Blob and data column sidecars were imported into the data availability checker without verifying block header signatures, potentially allowing unauthenticated or malicious blocks to corrupt storage caches.
Denial of Service: A deep or unfinalized chain of blocks could trigger O(n^2) recursive traversals during fork-choice processing, resulting in stack overflows or severe CPU exhaustion.
