DescriptionCVE.org

The UsersWP - Front-end login form, User Registration, User Profile & Members Directory plugin for WP plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 1.2.63 via the 'user_id' parameter due to missing validation on a user controlled key. This makes it possible for authenticated attackers, with editor-level access and above, to reset and permanently delete the avatar or banner image of any arbitrary user, including administrators, by clearing their avatar_thumb or banner_thumb metadata in the uwp_usermeta table.

AnalysisAI

Insecure Direct Object Reference in the UsersWP WordPress plugin (versions through 1.2.63) allows authenticated editor-level users to permanently delete or reset the avatar and banner images of any WordPress user account, including site administrators, by supplying an arbitrary user_id parameter. The vulnerability lies in missing authorization validation on the user_id key within image management handlers across class-forms.php, class-userswp.php, and class-profile.php, directly manipulating the uwp_usermeta table. No public exploit has been identified at time of analysis, and real-world severity is constrained by the high-privilege authentication prerequisite.

Technical ContextAI

The affected component is the UsersWP plugin for WordPress (CPE: cpe:2.3:a:stiofansisland:userswp_-_front-end_login_form,_user_registration,_user_profile_&_members_directory_plugin_for_wp:*:*:*:*:*:*:*:*). The root cause is CWE-639 (Authorization Through User-Controlled Key): the plugin's image reset and delete functions in class-forms.php (lines 89, 371, 389), class-userswp.php (line 574), and class-profile.php (line 1739) accept a user-supplied user_id parameter and use it to directly locate and clear avatar_thumb or banner_thumb metadata rows in the uwp_usermeta custom database table, without verifying that the authenticated user is authorized to modify the targeted account. This is a classic IDOR pattern where an object reference (user_id) is trusted without an ownership or permission check against the session context.

RemediationAI

An upstream fix has been committed to the AyeCode GitHub repository at https://github.com/AyeCode/userswp/commit/0e69f967578904cc26fadd0206270d50b7420298; however, the specific released patched plugin version number is not independently confirmed from available data - administrators should update to the latest version available in the WordPress plugin repository and verify it includes or supersedes this commit. As a compensating control until patching is confirmed, restrict editor-role assignments exclusively to fully trusted personnel, since the vulnerability requires editor-level WordPress authentication. Auditing existing editor accounts for necessity is advisable. Disabling front-end profile image upload/delete functionality via plugin settings, if available, would eliminate the attack surface with the trade-off of removing that feature for all users.
