Authentication Bypass in ARMember Premium (WordPress plugin) (CVE-2026-5076)
Summary
Authentication bypass in ARMember Premium (WordPress plugin) (CVE-2026-5076). Successful exploitation can lead to full system takeover. Exploitable via arm_reset_password_key.
Original description
The description as published by the source.
The ARMember Premium plugin for WordPress is vulnerable to an insecure password reset mechanism in all versions up to, and including, 7.3.1. The plugin stores a plaintext copy of the password reset key in the arm_reset_password_key user meta field when a user requests a password reset. This is in addition to the hashed key that WordPress core stores securely in wp_users.user_activation_key. The plaintext key stored in wp_usermeta can be used with the plugin's custom armrp reset action to set a new password for any user. Combined with another vulnerability such as SQL Injection (CVE-2026-5073, CVE-2026-5074), this makes it possible for unauthenticated attackers to extract the plaintext reset key and take over any user account, including administrators.
