Attack-Flow Graph

Executive Summary

The WP YouTube Lyte WordPress plugin before version 1.7.31 has a flaw where it does not properly escape certain attributes in YouTube embed blocks. This allows users with a contributor role or higher to inject malicious scripts that get stored and executed when the block is rendered, enabling Stored Cross-Site Scripting (XSS) attacks.

Detection Guidance

Check the installed version of the WP YouTube Lyte plugin. If it is below 1.7.31, the system is vulnerable. Use WordPress admin panel or run a command like 'wp plugin list' if using WP-CLI to verify the version.

Impact Analysis

This vulnerability could allow attackers with contributor-level access to inject and execute malicious scripts on your WordPress site. This may lead to unauthorized actions, data theft, or defacement of your website. Users visiting affected pages could have their sessions compromised or be redirected to malicious sites.

Compliance Impact

This vulnerability could lead to data breaches or unauthorized access, which may violate GDPR and HIPAA compliance requirements. GDPR mandates protecting user data, while HIPAA requires safeguarding protected health information. A successful exploit could result in non-compliance, legal penalties, or reputational damage.

Mitigation Strategies

Update the WP YouTube Lyte plugin to version 1.7.31 or later to fix the vulnerability. This prevents stored XSS attacks by properly escaping attributes in YouTube embed blocks.
