Name of the Vulnerable Software and Affected Versions The Beaver Builder – WordPress Page Builder versions up to, and including, 2.5.5.2

Description The issue is related to Stored Cross-Site Scripting via the Image URL value in the Media block due to insufficient input sanitization and output escaping. This allows authenticated attackers with access to the Beaver Builder 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, 2.5.5.2, consider disabling the Media block or restricting access to the Beaver Builder editor until a patch is available to prevent exploitation. As a temporary workaround, avoid using the Image URL value in the Media block to minimize the risk of Stored Cross-Site Scripting attacks.
