CVE-2023-4916Network attack vector

Password change via missing nonce validation

Published Sep 13, 2023 · Updated Apr 8, 2026

Cross-site request forgery in OTP Login With Phone Number 1.5.6 and earlier allows remote attackers to change a user's password. The lwp_update_password_action function accepts a password-change request without verifying a WordPress nonce, so an attacker-controlled request executes in the administrator's session. Exploitation requires a site administrator to open a crafted link or page, and the resulting password change can deny the affected user account access.
