The Element Pack Elementor Addons plugin for WordPress suffers from a stored cross-site scripting vulnerability (CWE-79) via the 'end_redirect_link' parameter. This flaw allows authenticated users with contributor or higher privileges to inject arbitrary JavaScript code into pages. The vulnerability exists due to improper neutralization of input during web page generation, specifically insufficient sanitization and escaping of user-supplied data. 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. No patch or official fix has been documented in the provided data. The plugin is not a cloud service, so remediation depends on vendor updates or manual mitigation.

Successful exploitation allows an authenticated contributor or higher to inject malicious scripts that execute in the context of other users viewing the affected pages. This can lead to unauthorized disclosure of information and modification of content, impacting confidentiality and integrity. There is no indication of availability impact. No known active exploits have been reported.

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