CVE-2024-8273Network attack vector

Identity spoofing via undisclosed authentication bypass

Published Dec 11, 2025 · Updated Dec 11, 2025

Authentication bypass in HYPR Server before 10.1 allows remote attackers to spoof identities through network authentication requests. HYPR has not published the affected endpoint, trusted identity attribute, or validation error that permits the spoofing. Exploitation requires active user interaction but no prior privileges and can expose protected data or interrupt dependent services.
