AI Security Review
scanned 5d ago · by lpm-firewall-aiThe evaluation path automatically routes OPENAI_API_KEY to the hardcoded api.layofflabs.com endpoint for matching model names. Although this requires running the evaluation command, the external credential destination is selected by package code rather than by the user.
Static reason
High-risk behavior combination matched malicious policy.; previous stored version diff introduced dangerous source
Trigger
Explicitly run the evaluation collector with a configuration whose model matches the internal-model pattern; provider selection happens automatically.
Impact
The external provider receives the OpenAI API key, which could enable unauthorized use of the account.
Mechanism
It sets the provider base URL to https://api.layofflabs.com/v1 and configures Codex to obtain the provider credential from OPENAI_API_KEY.
Attack narrative
When the evaluation collector encounters an internal-style model name, it selects the layofflabs provider without requiring an explicit provider selection. It configures Codex to use api.layofflabs.com and supplies OPENAI_API_KEY as that provider's credential. Running the evaluation command therefore sends the OpenAI key to a host other than OpenAI, without a user-facing consent step.
AI rationale
The evaluation path automatically routes OPENAI_API_KEY to the hardcoded api.layofflabs.com endpoint for matching model names. Although this requires running the evaluation command, the external credential destination is selected by package code rather than by the user.

Decision evidence
public snapshotAI called this Malicious at 92.0% confidence as Malware with low false-positive risk.
Evidence for block
- The evaluation collector reads OPENAI_API_KEY as its default API credential.
- For model names matching its internal-model pattern, the collector automatically selects the layofflabs provider and hardcodes api.layofflabs.com as its base URL.
- The collector passes the API key environment variable to Codex as the selected provider's env_key, then invokes Codex with those arguments.
- The evaluation script runs the collector over its selected configurations when explicitly invoked.
Evidence against
- The credential flow is in evaluation code, not the package's import entry point.
- The postinstall hook is a no-op for local installs; global installs hydrate the package's native runtime.

Affected versions and remediation
This report applies to oh-my-codex@0.21.43.
The versions list below shows the verdict for each recorded version.
- Avoid installing oh-my-codex@0.21.43. Remove it from direct dependencies and check your lockfile for transitive copies.
- Choose an independently verified alternative or release. This report does not establish that other versions are safe.
- If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment.
