Executive Summary

This vulnerability is a Stored Cross-Site Scripting (XSS) flaw in the LiveJournal Shortcode WordPress plugin version 1.1.1 or below. It occurs because the plugin does not properly validate or escape certain shortcode attributes before displaying them on a page or post. Attackers with contributor-level access or higher can exploit this by injecting malicious scripts via shortcode attributes.

Detection Guidance

Check for the LiveJournal Shortcode plugin version 1.1.1 or below in your WordPress installation. Look for suspicious shortcode usage in posts or pages, such as `[lj user='cow" onmouseover="alert(1)"']`. Review user roles with contributor access or higher for unauthorized script injections.

Impact Analysis

An attacker could execute arbitrary JavaScript code when users view the affected page or post. This could lead to session hijacking, defacement of the website, or theft of sensitive user data. The impact depends on the privileges of the compromised user account.

Compliance Impact

This vulnerability could lead to unauthorized access to user data, which may violate GDPR or HIPAA requirements for data protection and security. Organizations using this plugin may face compliance risks if the vulnerability is exploited to access or leak personal or health information.

Mitigation Strategies

Disable or remove the LiveJournal Shortcode plugin immediately. Update to the latest version if a patch is released. Restrict contributor roles to trusted users only. Monitor posts and pages for unauthorized script injections.
