CVE-2025-10293Network attack vector

Subscriber-to-Administrator takeover via misbound authentication tokens

Published Oct 15, 2025 · Updated Oct 15, 2025

Improper authentication in Nexist Keyy Two Factor Authentication 1.2.3 and earlier allows remote authenticated users to take over accounts. The token-generation flow fails to validate the requesting user's identity against the identity associated with the generated authentication token. Subscriber-level access is required, and administrator takeover succeeds only when the target administrator has Keyy two-factor authentication configured.
