58 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.
Consensus Bypass: Multiple fixes address disabled or incomplete validation of PoW, nonce, gas limit, uncle hash, and header fields, allowing invalid blocks to enter the chain. The critical severity stems from direct chain state corruption and network divergence.
Cryptographic Weakness: Weaknesses include predictable nonces, malleable signatures, custom curve implementations, and insecure key store encryption. These undermine the core cryptographic trust assumptions of the system.
Auth Bypass: Bypasses in signing authorization, JWT handling, sender validation, fork transition, and peer trust checks could allow unauthorized transactions, token abuse, or network manipulation.
