The Essential Addons for Elementor plugin for WordPress suffers from a stored cross-site scripting vulnerability (CWE-79) due to improper neutralization of input in the Filterable Controls label icon parameter. This allows authenticated users with contributor-level access or higher to inject arbitrary web scripts that persist and execute in the context of users viewing the compromised pages. The vulnerability affects all versions up to and including 5.9.8. The CVSS 3.1 base score is 6.4, reflecting network attack vector, low attack complexity, required privileges, no user interaction, scope change, and low impact on confidentiality and integrity. No patch or official fix has been documented in the provided data.

An attacker with contributor or higher privileges can exploit this vulnerability to inject persistent malicious scripts into pages generated by the plugin. These scripts execute in the browsers of users who access the infected pages, potentially leading to unauthorized actions or data exposure within the context of the affected site. The impact is limited to confidentiality and integrity with no availability impact. There are no known exploits in the wild currently.

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 limiting use of the vulnerable Filterable Controls feature to reduce risk.
