CVE-2024-2539 is a stored cross-site scripting vulnerability in the Livemesh Addons by Elementor WordPress plugin. It results from insufficient input sanitization and output escaping of the '_id' widget attributes, allowing authenticated users with contributor-level permissions or above to inject arbitrary JavaScript code. This code executes in the context of any user who views the compromised page, potentially leading to session hijacking or other script-based attacks. The vulnerability affects all versions up to 8.3.6. The CVSS 3.1 base score is 6.4 (medium severity), with attack vector network, low attack complexity, privileges required at the level of a contributor, no user interaction needed, and impacts on confidentiality and integrity but not availability. No patch or official fix has been documented yet.

An attacker with contributor-level access or higher can inject persistent malicious scripts into pages via the '_id' widget attribute. These scripts execute in the browsers of users who visit the affected pages, potentially compromising user sessions or data confidentiality and integrity. The vulnerability does not impact availability. There are no known active exploits reported.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, limit contributor-level access to trusted users only and consider removing or disabling the vulnerable plugin if possible. Monitor for updates from the vendor regarding patches or mitigations.
