Twitter Bootstrap Collapse WordPress Plugin Stored Cross-Site Scripting Vulnerability

A stored cross-site scripting vulnerability has been identified in the Twitter Bootstrap Collapse (Accordion) Shortcode WordPress plugin, affecting versions through 1.0. The vulnerability arises because the plugin fails to properly validate and escape certain shortcode attributes before rendering them on pages or posts. This oversight enables users with contributor roles and above to inject malicious scripts that are stored and executed later.

Impact

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