CVE-2026-7475 Details
Description
The Sky Addons plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the `sky-custom-scripts` custom post type in all versions up to, and including, 3.3.2. This is due to the custom post type being registered with `capability_type => 'post'` and `show_in_rest => true`, combined with insufficient input sanitization on the `sky_script_content` meta field and lack of output escaping when rendering scripts on the frontend. This makes it possible for authenticated attackers, with Author-level access and above, to inject arbitrary web scripts via the REST API that execute on every frontend page for all site visitors.
A stored cross-site scripting vulnerability has been identified in the Sky Addons plugin for WordPress, affecting all versions through 3.3.2. The issue arises in the 'sky-custom-scripts' custom post type, which is registered with 'capability_type' set to 'post' and 'show_in_rest' enabled. This configuration, coupled with inadequate input sanitization of the 'sky_script_content' meta field and insufficient output escaping when scripts are rendered on the frontend, allows authenticated attackers with Author-level access and above to inject arbitrary web scripts via the REST API. These scripts execute on every frontend page, impacting all site visitors.
Users are advised to update the Sky Addons WordPress plugin to version 3.3.3 or a newer patched version.
