Recurring patterns

The bug types that recur here, drawn from past fixes, not open vulnerabilities.

Auth Bypass: The CBFT consensus engine has suffered from numerous authorization bypasses, including integrating header verification without signature checks and processing unverified WAL consensus messages. This creates a risk of nodes accepting falsified blocks or falling out of consensus.

Cryptography: ECDSA signature and key generation logic relied on weak, home-brewed entropy mixing mechanisms and lacked deterministic nonce generation (RFC6979), exposing private keys to recovery attacks from repeated nonces.

Integer Overflow: The EVM execution and gas calculation engines historically lacked strict 64-bit integer bounds checking during arithmetic operations, allowing resource consumption and execution bypass via integer overflows.
