Summary
The The AMP for WP – Accelerated Mobile Pages plugin for WordPress is vulnerable to arbitrary shortcode execution in all versions up to, and including, 1.1.18. This is due to the software allowing users to execute an action that does not properly validate a value before running do_shortcode. This makes it possible for authenticated attackers, with custom-level access and above, to execute arbitrary shortcodes. The vulnerable output block is gated by the 'ampforwp-cat-description' setting, which is enabled by default, meaning the vast majority of installations are affected without any additional configuration change.
