Description

The User Registration plugin for WordPress is vulnerable to arbitrary file uploads due to a hardcoded encryption key and missing file type validation on the &#39;ur_upload_profile_pic&#39; function in versions up to, and including, 3.0.2. This makes it possible for authenticated attackers with subscriber-level capabilities or above to upload arbitrary files on the affected site&#39;s server which may make remote code execution possible. This was partially patched in version 3.0.2 and fully patched in version 3.0.2.1.
