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.
