Name of the Vulnerable Software and Affected Versions Visual Composer Website Builder plugin for WordPress versions up to, and including, 45.0

Description The issue is related to Stored Cross-Site Scripting via the post/page Title value due to insufficient input sanitization and output escaping. This allows authenticated attackers with access to the visual composer editor to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

Recommendations For versions up to, and including, 45.0, update to a version that addresses the insufficient input sanitization and output escaping issue to prevent Stored Cross-Site Scripting attacks. As a temporary workaround, consider restricting access to the visual composer editor to minimize the risk of exploitation.
