Am I affected?

Redux Framework redux-framework

  1. Affected≤ 4.2.12
  2. Patched in4.2.13

Update to 4.2.13 or newer.

You are affected if you run ≤ 4.2.12. Version 4.2.13 and later are not affected by this issue.

  • Check your version: in wp-admin go to Plugins → Installed Plugins and read the version under Redux Framework.
  • No admin access? Run a passive check of your site. It reads public files only.

What to do

  1. Update to version 4.2.13, or a newer patched version
  2. Rotate administrator passwords and application secrets if the site ran a vulnerable version while publicly reachable.
  3. Watch Redux Framework to get an email when the next vulnerability is published.

Advisory

Source description from Wordfence Intelligence, credited to Ram.

The Gutenberg Template Library & Redux Framework plugin <= 4.2.12 for WordPress used an incorrect authorization check in the REST API endpoints registered under the “redux/v1/templates/” REST Route in “redux-templates/classes/class-api.php”. The `permissions_callback` used in this file only checked for the `edit_posts` capability which is granted to lower-privileged users such as contributors, allowing such users to install arbitrary plugins from the WordPress repository and edit arbitrary posts.
