CVE-2024-4459 is a stored cross-site scripting vulnerability in the Themesflat Addons For Elementor WordPress plugin affecting all versions up to 2.1.2. The issue arises from insufficient sanitization and escaping of user-supplied input in widget titles, allowing authenticated users with contributor or higher privileges to inject arbitrary scripts. These scripts execute in the context of any user viewing the compromised pages, potentially leading to session hijacking or other script-based attacks. The vulnerability is tracked under CWE-87 (Improper Neutralization of Alternate XSS Syntax). The CVSS 3.1 base score is 6.4, reflecting network attack vector, low attack complexity, required privileges at the contributor level, no user interaction, and impacts on confidentiality and integrity.

An attacker with contributor-level or higher access can inject persistent malicious scripts into widget titles, which execute in the browsers of users who visit the affected pages. This can lead to unauthorized actions performed on behalf of users, disclosure of sensitive information, or other client-side impacts. The vulnerability does not affect availability. There are no reports of known exploits in the wild.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict contributor-level access to trusted users only and consider removing or disabling the vulnerable plugin if possible. Monitor for plugin updates from Themesflat that address this vulnerability.
