Recurring patterns

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

Auth Bypass: Consensus clients failed to strictly validate supermajority thresholds, which could allow invalid consensus proofs to be accepted. Developers must ensure that all consensus verifiers execute strict cryptographic validation and threshold checks.

Arbitrary Call Execution: Low-level message dispatch allowed arbitrary call execution when target payloads were unstructured. Strict structuring of destination calls is necessary to prevent message misrouting and execution manipulation.

Double Spend: Re-entrancy and batch-processing could allow requests or responses to be dispatched multiple times. Verifying commitment and receipt states immediately prior to callback execution is essential to neutralize double-dispatch risks.
