## RustChain Node Security Audit: Bounty Program Reveals 5 Critical Test Cases for SQLi, Double-Spend, Auth Bypass
A public bounty program for the RustChain node has exposed a targeted security audit test suite, revealing five specific, high-risk vulnerability vectors. The program, offering a 100 RTC reward, has generated automated tests for critical flaws including SQLite injection in the UTXO database, a double-spend (TOCTOU) vulnerability in transaction endpoints, and an authentication bypass in the core integration module. This structured audit moves beyond generic scanning, pinpointing exploitable code paths within the node's operational logic.

The test suite, documented in a GitHub issue, details each vulnerability's location and risk level. The most severe 'Critical' tests target `node/utxo_db.py` for SQL injection and `node/utxo_endpoints.py` for a time-of-check-to-time-of-use (TOCTOU) double-spend flaw. Additional 'High' risk tests cover a denial-of-service via resource exhaustion in the P2P gossip layer and an authentication bypass in the main integration file. A 'Medium' risk test also addresses potential hardware fingerprint spoofing in miner checks.

The existence of this formalized test suite signals a proactive but public-facing security push for the RustChain node. The methodology emphasizes non-destructive, automated testing designed for local instances and CI/CD integration. However, the public listing of these precise attack vectors, while part of a bounty claim process, inherently broadcasts potential weaknesses to a wider audience, including malicious actors, increasing the pressure for rapid patching by the development team.
