The Reales WP STPT plugin for WordPress is vulnerable to privilege escalation via account takeover in all versions up to, and including, 2.1.2. This is due to the plugin not properly validating a user's identity prior to updating their details like password. This makes it possible for authenticated attackers, with subscriber-level access and above, to change arbitrary user's passwords and email addresses, including administrators, and leverage that to gain access to their account. This can be combined with CVE-2025-3609 to achieve remote code execution as an originally unauthenticated user with no account.
The system's authorization functionality does not prevent one user from gaining access to another user's data or record by modifying the key value identifying the data.
