Name of the Vulnerable Software and Affected Versions Bold Page Builder plugin for WordPress versions up to, and including, 5.3.6

Description The issue is related to Stored Cross-Site Scripting via the additional settings parameter due to insufficient input sanitization and output escaping. This allows authenticated attackers with Contributor-level access and above to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

Recommendations For versions up to, and including, 5.3.6, update to a version that includes the necessary input sanitization and output escaping to prevent Stored Cross-Site Scripting attacks. As a temporary workaround, consider restricting access to the additional settings parameter to minimize the risk of exploitation.
