CRITICAL 9.9

User Registration <= 3.0.2 - Authenticated (Subscriber+) Arbitrary File Upload

CVSS Score

EPSS Percentile
0th

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 'ur_upload_profile_pic' 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'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.
