The yeashir Anber Elementor Addon plugin for WordPress suffers from a stored cross-site scripting vulnerability (CWE-79) due to improper neutralization of input during web page generation. Specifically, the $item['button_link']['url'] parameter is not sufficiently sanitized or escaped, allowing authenticated users with Contributor-level privileges or higher to inject arbitrary JavaScript code. This malicious code executes in the context of any user who views the compromised page, potentially leading to session hijacking or other client-side attacks. The vulnerability affects all plugin versions up to 1.0.1. The CVSS 3.1 score of 6.4 reflects a medium severity with confidentiality and integrity impacts but no availability impact. There is no indication of an official patch or vendor advisory at this time, and no known exploits have been observed in the wild.

An authenticated attacker with Contributor-level access or higher can exploit this vulnerability to inject and store malicious scripts within pages generated by the plugin. These scripts execute in the browsers of users who visit the infected pages, potentially compromising user sessions or data confidentiality and integrity. The vulnerability does not affect availability. No known active exploitation has been reported.

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 disabling or removing the Anber Elementor Addon plugin if feasible. Monitor for updates from the vendor regarding patches or official mitigations.
