CVE-2024-0448: 
WordPress vulnerability analysis and mitigation

The Elementor Addons by Livemesh plugin for WordPress contains a Stored Cross-Site Scripting vulnerability (CVE-2024-0448) affecting all versions up to and including 8.3.1. The vulnerability was discovered and disclosed in January 2024, affecting the plugin's widget URL parameters due to insufficient input sanitization and output escaping (NVD).

The vulnerability stems from inadequate input sanitization and output escaping in the plugin's widget URL parameters. This security flaw has been assigned a CVSS v3.1 base score of 5.4 (Medium) by NIST with a vector string of CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N, while Wordfence assigned a slightly higher score of 6.4 (Medium) with vector string CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N (NVD).

When exploited, this vulnerability allows authenticated attackers with contributor-level access or higher to inject arbitrary web scripts into pages. These malicious scripts will execute whenever a user accesses the compromised page, potentially leading to data theft, session hijacking, or other malicious actions (NVD).

Website administrators using the Elementor Addons by Livemesh plugin should immediately update to a patched version of the plugin. The vulnerability has been addressed in newer releases, as evidenced by the patch commit (WordPress Plugin Patch).
