description

HarnessRouter Docker images before 0.37.17 do not properly enforce session file boundaries. An attacker with an instance API key or authenticated console access can read files accessible to the service, potentially exposing stored secrets; in a specific Codex resume configuration, an agent may also cause writes outside its session. The read issue requires credentials associated with a session the caller can control.

mitigation

Upgrade the HarnessRouter Docker image to 0.37.17. If API keys or console access may have been exposed, rotate the secret key, console password, API keys, provider credentials, and other connected-service credentials, then restart the container.

fixed in 0.37.17
