This vulnerability (CVE-2024-27986) in Livemesh Elementor Addons (up to version 8.3.5) is a stored cross-site scripting (CWE-79) issue caused by improper input neutralization during web page generation. An attacker with low privileges and requiring user interaction can inject malicious scripts that may lead to partial confidentiality, integrity, and availability impacts. The CVSS 3.1 vector is AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:L, reflecting network attack vector, low attack complexity, low privileges required, user interaction required, scope changed, and low impacts on confidentiality, integrity, and availability. No patch or official remediation level has been published yet.

Successful exploitation allows an attacker with low privileges to inject and store malicious scripts that execute in the context of other users' browsers, potentially leading to partial disclosure of information, modification of data, or disruption of service. The scope of impact is changed, meaning the vulnerability affects resources beyond the initially vulnerable component. However, the impact is rated as low for confidentiality, integrity, and availability.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, users should consider limiting privileges of users who can input content and apply web application firewall (WAF) rules to detect and block XSS payloads. Monitor vendor channels for updates and apply patches promptly once available.
