Name of the Vulnerable Software and Affected Versions The Beaver Builder – WordPress Page Builder plugin versions up to, and including, 2.8.1.1

Description The issue is related to Stored Cross-Site Scripting due to insufficient input sanitization and output escaping, allowing authenticated attackers with contributor access or higher to inject arbitrary web scripts in pages. This can be achieved via the link target parameter. The injected scripts will execute whenever a user accesses an injected page.

Recommendations For versions up to, and including, 2.8.1.1, 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 link target parameter to minimize the risk of exploitation.
