Ziggeo WordPress Plugin Stored Cross-Site Scripting Vulnerability

A stored cross-site scripting vulnerability has been identified in the Ziggeo plugin for WordPress, affecting all versions through 3.1. This issue arises from inadequate input sanitization and output escaping of user-supplied attributes in the 'ziggeo_event' shortcode. As a result, authenticated attackers with contributor-level access or higher can inject arbitrary scripts into pages, which will execute when users access those 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 Ziggeo WordPress Plugin version 3.1.1 or a newer patched version to address this vulnerability.
