Devtron is an open source tool integration platform for Kubernetes. In version 2.0.0 and prior, a vulnerability exists in Devtron's Attributes API interface, allowing any authenticated user (including low-privileged CI/CD Developers) to obtain the global API Token signing key by accessing the /orchestrator/attributes?key=apiTokenSecret endpoint. After obtaining the key, attackers can forge JWT tokens for arbitrary user identities offline, thereby gaining complete control over the Devtron platform and laterally moving to the underlying Kubernetes cluster. This issue has been patched via commit d2b0d26.

  • →Monitor HTTP requests to the /orchestrator/attributes endpoint with the query parameter key=apiTokenSecret, especially from low-privileged user accounts (CI/CD Developer roles), as this is the specific endpoint abused to extract the JWT signing secret. ↗
  • →After key extraction, attackers forge JWT tokens offline for arbitrary user identities. Detect anomalous JWT usage patterns such as tokens for high-privileged users (admin) originating from sessions that previously authenticated as low-privileged CI/CD Developer accounts. ↗
  • ·The global API Token signing key (apiTokenSecret) is retrievable via the Attributes API by any authenticated user. If this key has been exposed, all existing JWT tokens should be considered compromised and the signing key must be rotated immediately. ↗
