WP Responsive Tabs Stored Cross-Site Scripting Vulnerability

A stored cross-site scripting vulnerability has been identified in the WP Responsive Tabs plugin for WordPress, affecting all versions through 1.2.9. The issue arises from inadequate input sanitization and output escaping of user-supplied attributes in the 'wprtabs' shortcode. This vulnerability allows authenticated attackers with contributor-level access and above to inject arbitrary scripts into pages, which are executed when users access the affected pages.

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.

Remediation

Users can update to WP Responsive Tabs version 1.3.0 or later to address this vulnerability.
