  "title": "Cross-workspace authorization bypass in HarnessRouter",
  "summary": "HarnessRouter 0.4.2 through 0.31.6 does not consistently apply workspace boundaries when handling session and response identifiers. A holder of a non-default workspace API key who obtains an identifier from another workspace in the same organization may access or alter that workspace's session-related data, including deleting or sharing sessions. Organization-to-organization access is not implicated.",
  "mitigation": "Upgrade HarnessRouter to version 0.31.7 or later. Until upgraded, distribute API keys only to principals trusted to access all workspaces in the organization.",
