CVE-2025-15001Network attack vectorHinoki check available

Unauthenticated account takeover via unchecked password update

Published Jan 6, 2026 · Updated Jan 6, 2026

Authentication bypass in FS Registration Password 1.0.1 and earlier allows remote attackers to take over WordPress accounts. The Auth.php registration handler accepts a user-controlled account key and updates that account's password without confirming the requester's identity. No authentication or user interaction is required, and targeting an administrator account grants administrative access.
