The Plus Addons for Elementor Stored Cross-Site Scripting Vulnerability

A stored cross-site scripting vulnerability has been identified in the Plus Addons for Elementor WordPress plugin, specifically in the Progress Bar shortcode. This issue affects all versions up to and including 6.4.9. The vulnerability arises from inadequate input sanitization and output escaping of user-supplied attributes, allowing authenticated attackers with contributor-level access or higher to inject arbitrary web scripts. These scripts would execute when a user accesses the compromised page.

Remediation

Users are advised to update the Plus Addons for Elementor plugin to version 6.4.10 or a newer patched version.
