Eventer <= 4.4.2 - Insecure Password Reset Mechanism to Unauthenticated Privilege Escalation

The Eventer plugin for WordPress is vulnerable to an insecure password reset mechanism in all versions up to, and including, 4.4.2. The plugin stores a plaintext copy of the password reset key in the eventer_verification_code user meta field when a user requests a password reset. The plaintext key stored in wp_usermeta can be used with the plugin's custom reset action to set a new password for any user. Combined with another vulnerability such as SQL Injection (CVE-2026-9700), this makes it possible for unauthenticated attackers to extract the plaintext reset key and take over any user account, including administrators. Note: The password reset function only works up to PHP version 7.4.
