Recurring patterns

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

Auth Bypass: Multiple fixes address bypasses in node-level permissioning across discovery, connection acceptance, and ongoing connection checks. Inconsistent enforcement between discovery and connection paths allows unauthorized peers to connect or maintain connections.

Denial of Service: Unbounded request sizes, batch sizes, frame sizes, connection counts, and trace/filter ranges repeatedly caused resource exhaustion. Each API surface needs explicit caps.

Consensus Bypass: Multiple consensus validation gaps (EIP-1559 fee/gas limits, round number consistency, duplicate seals, mixhash) allowed invalid blocks or transactions to be accepted, risking forks.
