CVE-2026-24178Network attack vector

Unauthenticated authorization bypass via user-controlled key

Published Apr 28, 2026 · Updated Apr 28, 2026

Authorization bypass in NVIDIA NVFlare Dashboard before 2.7.2 allows remote attackers to gain elevated access via a user-controlled key. The user management and authentication system accepts a user-controlled key in an authorization decision, but NVIDIA has not disclosed the affected endpoint or missing validation. No account or user interaction is required, and successful bypass grants privileges that can expose or alter data, execute code, or interrupt the service.
