CVE-2025-0640Network attack vector

Service degradation via user-controlled authorization key

Published Sep 2, 2025 · Updated Jun 6, 2026

Authorization bypass in AKINSOFT OctoCloud allows remote authenticated users with high privileges to trigger resource leakage. The published record identifies a user-controlled key as the authorization bypass but discloses no endpoint, parameter, resource type, or failed authorization check. High-privileged network access is required; repeated triggering can accumulate leaked resources and degrade service availability.
