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 versions through 6.1.8. The issue arises in the Table Widget's 'searchable_label' parameter, where inadequate input sanitization and output escaping allow authenticated attackers with Contributor-level access or higher to inject arbitrary scripts. These scripts are executed when a user views the affected page.

Impact

Exploitation of this vulnerability allows for stored cross-site scripting, where injected scripts are executed in the context of the user viewing the page.

Reproduction

To reproduce this vulnerability, an authenticated user with Contributor-level access or higher can inject scripts through the Table Widget's 'searchable_label' parameter. The lack of proper sanitization and escaping allows these scripts to be executed when the page is accessed.

Remediation

Users are advised to update the plugin to version 6.2.0 or later, where this vulnerability has been patched.
