Securing AI Trading Systems: Overriding Transitive NPM Vulnerabilities and RLHF Optimization

security: override vulnerable transitive npm deps

Developer Igor Ganapolsky is building an automated AI trading system in public using Reinforcement Learning from Human Feedback. The system currently maintains a 50% success rate after processing 110 feedback signals.

Why This Matters

In complex AI trading architectures, security vulnerabilities in transitive dependencies like systeminformation or cookie can compromise automated snapshots and financial data syncing. While theoretical models assume clean data, real-world implementations require continuous metric filtering, such as excluding undo-revert actions, to maintain a valid Beta-Bernoulli Thompson Sampling state with a 30-day decay.

Key Insights

• The system utilizes a Beta-Bernoulli Thompson Sampling model with alpha=1 and beta=1 to learn from feedback as of 2026.
• Transitive dependency overrides are used to mitigate security risks in packages like systeminformation and cookie.
• RLHF metrics are refined by excluding undo-revert actions to prevent noise in the success rate calculation.
• Automated chores synchronize dashboard data and Alpaca state snapshots to maintain system consistency.

Practical Applications

• Use Case: AI trading systems using Alpaca for automated snapshots and dashboard syncing.
• Pitfall: Including undo-revert actions in metrics leading to skewed RLHF success rates.
• Use Case: Managing security in Node.js environments by manually overriding vulnerable transitive dependencies.
• Pitfall: Neglecting decay factors in Thompson Sampling resulting in outdated feedback influencing current trading logic.
