CVE-2026-82816Public exploitNetwork attack vector

Authenticated cross-session access via user-controlled key

Published Aug 31, 2026 · Updated Aug 31, 2026

Improper authorization in Diboot 3.8.0 allows remote authenticated users to access other users' AI sessions through /api/ai-session/. The endpoint uses a user-controlled record key without confirming that the requesting account owns the selected session; the exact parameter and code path are undisclosed. Low-privileged access and network reachability are required, and exploitation can read, alter, or interrupt another user's AI-session data.
