  "title": "Authorization bypass in HarnessRouter console proxy",
  "summary": "HarnessRouter versions before 0.31.8 are affected when a non-self-hosted console serves multiple organizations. A remote caller who can reach the console may access privileged organization configuration routes with an invalid bearer value, potentially redirecting provider traffic and influencing later tasks. Default self-hosted installations are not affected.",
  "mitigation": "Upgrade HarnessRouter to version 0.31.8 or later. Until upgraded, prevent external access to the console internal paths and organization connection and policy endpoints.",
