Detailsinfo

A vulnerability was found in teydeastudio Password Policy Plugin up to 3.7.1. It has been declared as problematic. This vulnerability affects the function Module_Password_Hint::get_user of the component Password Hint Module. The manipulation of the argument role/user_login with an unknown input leads to a privileges management vulnerability. The CWE definition for the vulnerability is CWE-269. The product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor. As an impact it is known to affect integrity, and availability. CVE summarizes:

The WP Password Policy plugin for WordPress is vulnerable to Privilege Escalation in all versions up to and including 3.7.1. This is due to missing authorization checks and nonce verification in the `get_user()` function of the `Module_Password_Hint` class, which unconditionally calls `WP_User::set_role()` with the attacker-supplied `role` parameter on any account resolved via `$_POST['user_login']`, without confirming the requesting user holds the capability to assign roles. This makes it possible for authenticated attackers, with subscriber-level access and above, to escalate their own privileges to Administrator by submitting a crafted POST request — with `action` set to `createuser` and `role` set to `administrator` — to the password-reset form endpoint. The vulnerable code path is reachable via the `password_hint` filter hooked during the WordPress password-reset form render, meaning an attacker need only possess a valid password-reset cookie to reach the sink.

The advisory is available at wordfence.com. This vulnerability was named CVE-2026-15992 since 07/16/2026. The exploitation appears to be easy. The attack can be initiated remotely. Technical details are known, but there is no available exploit. The structure of the vulnerability defines a possible price range of USD $0-$5k at the moment (estimation calculated on 07/28/2026). This vulnerability is assigned to T1068 by the MITRE ATT&CK project.

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.
