CVE-2026-103908 Details
Description
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.
A vulnerability allowing arbitrary shortcode execution has been identified in the AMP for WP – Accelerated Mobile Pages plugin for WordPress, affecting all versions through 1.1.18. The issue arises because the plugin does not properly validate values before executing them with do_shortcode, allowing authenticated attackers with custom-level access or higher to execute arbitrary shortcodes. This vulnerability is particularly concerning as it impacts the 'ampforwp-cat-description' output block, which is enabled by default on most installations.
Users are advised to update the AMP for WP – Accelerated Mobile Pages plugin to version 1.1.19 or a newer patched version.
