The Plus Addons for Elementor plugin for WordPress suffers from a stored cross-site scripting vulnerability (CWE-79) due to improper neutralization of input in the 'res_width_value' parameter within the tp_page_scroll widget. This allows authenticated users with Contributor or higher privileges to inject arbitrary JavaScript code into pages, which executes when viewed by others. The vulnerability affects all versions up to and including 5.6.2. The CVSS 3.1 base score is 6.4, reflecting network attack vector, low attack complexity, privileges required, no user interaction, and impacts on confidentiality and integrity but not availability.

An attacker with Contributor-level or higher access can exploit this vulnerability to inject persistent malicious scripts into WordPress pages using the vulnerable plugin. This can lead to unauthorized actions performed in the context of other users viewing the page, potentially compromising user data confidentiality and integrity. There is no indication of availability impact. The vulnerability does not require user interaction to trigger once the malicious content is injected.

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 vulnerable plugin if possible. Monitor for plugin updates from posimyththemes and apply official patches promptly once available.
