The Plus Addons for Elementor plugin for WordPress suffers from a stored XSS vulnerability (CWE-79) via the searchable_label parameter in its Table Widget. This flaw allows authenticated users with Contributor or higher privileges to inject arbitrary JavaScript code that executes in the context of other users viewing the compromised page. The vulnerability exists due to improper input neutralization during web page generation, specifically lacking sufficient input sanitization and output escaping. The issue affects all versions up to and including 6.1.8. 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 with no availability impact.

An attacker with Contributor-level or higher access can exploit this vulnerability to inject malicious scripts into pages using the Table Widget's searchable_label parameter. These scripts execute in the browsers of users who visit the infected pages, potentially leading to unauthorized actions such as session hijacking or data theft within the scope of the affected site. The impact is limited to confidentiality and integrity, with no direct availability impact. There are no reports of active exploitation in the wild.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Since no official patch or vendor advisory is provided in the available data, users should monitor for updates from the plugin vendor posimyththemes. Until a fix is available, restrict Contributor-level access to trusted users only and consider disabling or limiting use of the Table Widget's searchable_label feature if feasible.
