Stored XSS in Sky Addons WordPress Plugin

Publication date: 2026-05-08

Last updated on: 2026-05-08

Assigner: Wordfence

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.

Executive Summary

The Sky Addons plugin for WordPress has a Stored Cross-Site Scripting (XSS) vulnerability in all versions up to and including 3.3.2. This vulnerability arises because the plugin registers a custom post type with certain capabilities and enables REST API access, but it does not properly sanitize input or escape output for the 'sky_script_content' meta field. As a result, authenticated users with Author-level access or higher can inject malicious scripts via the REST API, which then execute on every frontend page for all visitors.

Impact Analysis

This vulnerability allows attackers with Author-level access or higher to inject arbitrary web scripts that execute on the frontend for all site visitors. This can lead to theft of user data, session hijacking, defacement of the website, or distribution of malware to visitors. Because the attack is stored and executed on every page, it can affect all users who visit the site.

Compliance Impact

The vulnerability allows authenticated attackers with Author-level access to inject arbitrary scripts that execute on every frontend page for all site visitors. This can lead to unauthorized access to user data or manipulation of site content, potentially compromising confidentiality and integrity.

Such a security flaw could impact compliance with standards like GDPR and HIPAA, which require protection of personal data and prevention of unauthorized access or data breaches. Exploitation of this vulnerability might result in exposure of personal information or unauthorized actions on behalf of users, thereby violating these regulations.
