DescriptionCVE.org

The User Profile Builder - Beautiful User Registration Forms, User Profiles & User Role Editor plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Avatar Field in all versions up to, and including, 4.0.2 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with subscriber-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This is exploitable via a nonce-free GET request to /wp-admin/profile.php, requiring no profile-form submission; a Subscriber can plant the malicious attachment URL, which then executes when an administrator opens that user's Edit User screen.

AnalysisAI

Stored cross-site scripting in the WordPress plugin User Profile Builder (Profile Builder by Cozmoslabs) through version 4.0.2 lets any authenticated user with Subscriber-level access plant script content in their avatar value and have it execute in a higher-privileged user's browser. The distinguishing enabler is a nonce-free GET request to /wp-admin/profile.php that writes a malicious attachment URL as the avatar without any profile-form submission or valid nonce, so a Subscriber only needs to reach that endpoint to seed the payload. …
