The WPZOOM Addons for Beaver Builder plugin for WordPress suffers from a stored cross-site scripting vulnerability (CWE-79) in its Heading widget due to inadequate input sanitization and output escaping. This flaw permits authenticated users with contributor-level privileges or above to inject arbitrary JavaScript code that executes in the context of any user viewing the affected page. The vulnerability affects all plugin versions up to 1.3.4. The CVSS 3.1 base score is 6.4, reflecting network attack vector, low attack complexity, required privileges at the contributor level, no user interaction, and impacts on confidentiality and integrity with no availability impact. CVE-2024-30424 is likely a duplicate of this issue. No official patch or remediation guidance is currently available from the vendor.

An authenticated attacker with contributor-level access or higher can exploit this vulnerability to inject and execute arbitrary scripts in the context of users visiting the affected pages. This can lead to unauthorized actions such as session hijacking, defacement, or theft of sensitive information accessible to the victim user. The impact affects confidentiality and integrity but does not affect availability. There are no known active exploits reported in the wild.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict contributor-level access to trusted users only and consider disabling or removing the vulnerable Heading widget if feasible. Monitor vendor channels for updates and apply any released patches promptly.
