This vulnerability in WPZOOM Beaver Builder Addons (<= 1.3.4) is due to improper input sanitization during web page generation, leading to stored cross-site scripting (XSS). An attacker with low privileges can inject malicious scripts that may be executed in the context of other users, potentially impacting confidentiality, integrity, and availability. The CVSS 3.1 vector indicates network attack vector, low attack complexity, required privileges low, user interaction required, and scope changed, with low impact on confidentiality and integrity and low impact on availability.

Successful exploitation could allow an attacker to execute arbitrary scripts in the context of other users, potentially leading to data theft, session hijacking, or other malicious actions affecting confidentiality, integrity, and availability. The impact is rated medium based on the CVSS score of 6.5. There are no reports of active exploitation in the wild.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, limit user privileges to trusted users only and avoid accepting untrusted input that could be stored and rendered by the plugin. Monitor WPZOOM's official channels for updates and apply patches promptly once available.
