CVE-2024-8858 is a stored cross-site scripting vulnerability in the Livemesh Addons by Elementor WordPress plugin affecting all versions up to 8.5. The flaw exists due to improper neutralization of input in the 'piechart_settings' parameter, allowing authenticated users with Contributor or higher privileges to inject arbitrary scripts. These scripts execute in the context of users who view the compromised pages, potentially leading to session hijacking or other script-based attacks. The vulnerability is tracked under CWE-79. No known exploits in the wild have been reported, and no vendor patch or advisory is currently available.

Successful exploitation allows authenticated users with Contributor-level access or higher to inject persistent malicious scripts into pages. These scripts execute in the browsers of users who access the injected pages, potentially compromising user sessions or performing unauthorized actions. The vulnerability does not affect availability and has limited confidentiality and integrity impact as per the CVSS vector.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict Contributor-level access to trusted users only and consider disabling or limiting use of the affected plugin. Monitor official Livemesh or WordPress security advisories for updates.
