WordPress · Userswp · CVE-2026-12102
**Name of the Vulnerable Software and Affected Versions**
UsersWP versions prior to 1.2.64
**Description**
The UsersWP plugin for WordPress contains an Insecure Direct Object Reference (IDOR), which occurs when an application provides direct access to objects based on user-supplied input. The issue exists due to missing validation on a user-controlled key within the `user id` parameter. This allows authenticated attackers with editor-level access or higher to reset and permanently delete the avatar or banner image of any user, including administrators, by clearing the `avatar thumb` or `banner thumb` metadata in the `uwp usermeta` table.
**Recommendations**
Update the plugin to a version later than 1.2.63.
As a temporary workaround, restrict access to the `user id` parameter for users with editor-level permissions until the update is applied.
