If you discover a security vulnerability in Codex-Bridge, please report it privately via GitHub's Security Advisory system:
- Go to https://github.com/LeenixP/Codex-Bridge/security/advisories/new
- Describe the issue with as much detail as possible.
- Allow time for the maintainer to respond before public disclosure.
Do not file a public issue for security vulnerabilities.
Codex-Bridge runs as a local proxy on 127.0.0.1. The attack surface is limited to:
- The HTTP proxy server bound to localhost.
- The Electron desktop shell.
- Provider configuration files stored on disk.
- API keys are encrypted at rest using the OS keychain where available (
safeStorage). Keep your OS login credentials secure. - The proxy listens on 127.0.0.1 by default — do not change this to a public interface unless you understand the risks.
- Review provider base URLs before saving to avoid sending credentials to untrusted endpoints.
