The plugin’s postInsertUserProcess function lacks proper file path validation, allowing an authenticated user with Subscriber-level access or higher to specify any file path for deletion. This flaw enables the attacker to remove arbitrary files on the server, and deleting critical files such as wp-config.php could lead to remote code execution or major service disruption. The weakness is a classic path traversal and unauthorized file deletion vulnerability (CWE‑22). Based on the description, it is inferred that the attacker must have a valid user account with Subscriber-level permissions.

This issue affects the WordPress plugin User Meta – User Profile Builder and User management plugin in all releases up to and including version 3.1.2. Any WordPress installation using these versions is vulnerable if it has subscribers with permission to trigger the postInsertUserProcess routine.

The CVSS score of 8.0 signals a high severity, and the EPSS score of less than 1 % indicates a low probability of exploitation in the wild. The vulnerability is not presently listed in the CISA KEV catalogue. Based on the description, it is inferred that exploitation requires an authenticated attacker, so the attack vector is internal via account compromise or social engineering. Once the attacker deletes a critical file, the danger escalates to remote code execution or denial of service on the affected site.
