This vulnerability in livemesh Livemesh Addons for Beaver Builder (<= 3.9.2) allows stored cross-site scripting due to improper input neutralization during web page generation. An attacker with limited privileges can inject malicious scripts that persist and execute in the context of other users, potentially leading to information disclosure, session hijacking, or other impacts consistent with stored XSS. The CVSS 3.1 score of 6.5 reflects network attack vector, low attack complexity, required privileges, user interaction, and impacts on confidentiality, integrity, and availability at a low to low level. No patch or vendor advisory is provided in the data, and no known active exploitation is reported.

Successful exploitation can lead to execution of arbitrary scripts in the context of affected users, potentially resulting in information disclosure, session hijacking, or other impacts typical of stored XSS vulnerabilities. The impact is rated medium severity with low confidentiality, integrity, and availability impacts as per the CVSS vector. No known exploits in the wild have been reported.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, limit privileges of users who can input data into the affected plugin and consider applying web application firewall (WAF) rules to detect and block XSS payloads targeting this component.
