Is Eventer safe? Known vulnerabilities and latest version

Unauthenticated Cross Site Scripting (XSS) in Eventer <= 0.1.1 versions.

The Eventer plugin for WordPress is vulnerable to time-based SQL Injection via the ‘code’ parameter in all versions up to, and including, 4.4.2 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for unauthenticated attackers to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.

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.
