  • No admin access? Run a passive check of your site. It reads public files only.

What to do

  1. Update to version 12.0.3, or a newer patched version
  2. Rotate administrator passwords and application secrets if the site ran a vulnerable version while publicly reachable.
  3. Watch CSS & JavaScript Toolbox to get an email when the next vulnerability is published.

Advisory

Source description from Wordfence Intelligence, credited to Martin Herancourt.

The CSS & JavaScript Toolbox plugin for WordPress is vulnerable to Local File Inclusion in versions up to 12.0.3. This makes it possible for authenticated attackers, with subscriber-level access and above, to include and execute arbitrary files on the server, allowing the execution of any PHP code in those files. This can be used to bypass access controls, obtain sensitive data, or achieve code execution in cases where images and other “safe” file types can be uploaded and included.
