Name of the Vulnerable Software and Affected Versions Visual Composer Website Builder, Landing Page Builder, Custom Theme Builder, Maintenance Mode & Coming Soon Pages plugin for WordPress versions up to, and including, 45.6.0

Description The issue is related to Stored Cross-Site Scripting via the plugin's custom fields due to insufficient input sanitization and output escaping on user-supplied attributes. This allows authenticated attackers with contributor-level and above permissions to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

Recommendations For versions up to, and including, 45.6.0, update to a version higher than 45.6.0 to resolve the issue. As a temporary workaround, consider restricting access to the custom fields feature to minimize the risk of exploitation. Additionally, restrict permissions to prevent contributors and above from injecting malicious scripts.
