CVE-2025-64277Network attack vector

Unauthenticated service interruption via missing authorization

Published Nov 13, 2025 · Updated Nov 13, 2025

Missing authorization in QuantumCloud ChatBot 7.3.9 and earlier allows remote attackers to interrupt service via an unauthorized action. Patchstack and the CNA record do not identify the affected function, request, or authorization check, so the exact code-level mechanism is undisclosed. No account or user interaction is required, and the published consequence is limited to partial service interruption.
