Recurring patterns

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

Auth Bypass: The core integration node suffered from multiple high-severity auth bypasses, including unconfigured/empty admin keys in the environment permitting arbitrary unauthenticated admin access, and missing signature validations on block header ingestion.

Denial of Service: Memory exhaustion (OOM) and resource locking issues frequently impacted the UTXO database layer due to un-paginated fetchall database queries on the mempool and non-atomic SQL updates.

Deserialization of Untrusted Data: The use of pickle.loads in proof_of_iron to restore cached fingerprint feature objects created a high risk of Remote Code Execution (RCE) via untrusted inputs.
