Who should care

Defenders and administrators of Kaneo instances should assess exposure and implement compensating controls. Operators, security teams, and vulnerability management teams should review the vulnerability and implement necessary mitigations. Platform administrators should verify exposure and implement compensating controls to prevent unauthorized access to sensitive workspaces and resources.

Why it matters

The vulnerability allows authenticated users to access other workspaces, potentially leading to unauthorized data access, modification, or deletion.

  • Authenticated users may access sensitive workspaces and resources
  • Data may be read, modified, or deleted without authorization
  • Workspace contents may be searched without authorization
  • Defenders should verify exposure and implement compensating controls

Technical summary

The vulnerability allows authenticated users to access other workspaces by supplying project, task, label or workspace identifiers to API routes lacking membership checks. This issue affects Kaneo instances before version 2.1.6. The vulnerability has a CVSS score of 7.7 and is considered HIGH severity. Attackers who obtain identifiers, for example from shared project links, can read projects and tasks, modify or delete tasks, labels and comments, and search workspace contents. Defenders should prioritize verifying exposure and implementing compensating controls.

Defensive priority

Defenders should prioritize verifying exposure and implementing compensating controls, as the vulnerability allows authenticated users to access other workspaces.

Recommended defensive actions

  • Verify Kaneo version and implement compensating controls
  • Restrict access to sensitive workspaces and resources
  • Monitor for suspicious activity and implement logging
  • Review the supplied official advisory or CVE record to validate affected scope, severity, and vendor guidance.
  • Plan vendor-supported updates or mitigations through normal change control where exposure is confirmed.
  • Check relevant monitoring, detection, and logs for exposed assets that need extra review.
  • Track exceptions, retest remediated assets, and close the item only after evidence is documented.
