CVE-2026-12102: CWE-639 Authorization Bypass Through User-Controlled Key in stiofansisland UsersWP – Front-end login form, User Registration, User Profile & Members Directory plugin for WP
The UsersWP WordPress plugin is vulnerable to an authorization bypass issue due to missing validation on a user-controlled 'user_id' parameter. This flaw allows authenticated users with editor-level privileges or higher to reset and permanently delete avatar or banner images of any user, including administrators, by clearing specific user metadata. The vulnerability affects all versions up to and including 1.2.63. The CVSS score is low, reflecting limited impact confined to image metadata modification without broader data compromise or denial of service.

Technical Summary
CVE-2026-12102 is an Insecure Direct Object Reference vulnerability (CWE-639) in the UsersWP – Front-end login form, User Registration, User Profile & Members Directory plugin for WordPress. The vulnerability arises from missing validation on the 'user_id' parameter, which is user-controlled. Authenticated attackers with editor-level or higher privileges can exploit this to reset or delete avatar and banner images of arbitrary users by clearing their avatar_thumb or banner_thumb metadata in the uwp_usermeta table. This affects all plugin versions up to and including 1.2.63. The vulnerability does not impact confidentiality or availability but allows limited integrity modification of user profile images.
Potential Impact
An attacker with editor-level or higher privileges can modify or delete avatar and banner images of any user, including administrators, by exploiting the lack of validation on the 'user_id' parameter. This results in unauthorized modification of user profile metadata but does not disclose sensitive information, cause denial of service, or escalate privileges beyond existing access.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict editor-level access to trusted users only to reduce risk. Monitor vendor channels for updates or patches addressing this vulnerability.
