Audit Bun runtime security by applying pattern checks to Bun.serve, Bun.spawn, and Bun.file code paths to detect shell injection, command injection, and path traversal vulnerabilities. This enforces safe input validation and parameterized queries to uncover server misconfigurations.

Common Bun security vulnerabilities include unsafe command execution via Bun.spawn, unvalidated input in WebSocket handling, and path traversal through Bun.file operations. These issues can lead to shell injection, credential leakage, and open network exposure if not properly guarded.

Yes, you can use this audit to check Bun.serve configurations for misconfigurations. The audit evaluates server settings to identify open network exposure risks and enforces proper authentication before upgrades to prevent unauthorized access and credential leakage.

Integrate Bun security pattern checks into CI/CD pipelines by running the audit against your Bun-based project code paths. The audit provides actionable guidance and safeguards for development workflows, identifying shell and command handling issues alongside path traversal risks automatically.

The best way to prevent command injection in Bun applications is to enforce safe input validation, parameterized queries, and restricted network exposure across Bun.spawn and Bun.serve paths. Applying these security patterns mitigates unsafe command execution and shell injection risks.
