Description

The Gutenberg Template Library & Redux Framework plugin <= 4.2.11 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.

Affected WordPress components

A confirmed match is backed by the plugin or theme slug. A possible match is based on the product name only and should be verified.

Affected products and versions

  • Redux.io Gutenberg Template Library & Redux Framework — From 4.2.11 (including) to 4.2.11 (including)
  • redux gutenberg_template_library_\&_redux_framework — Up to and including 4.2.11
