Technical details
The Drag and Drop Multiple File Upload for Contact Form 7 plugin for WordPress (versions up to 1.3.9.7) is vulnerable to Stored Cross-Site Scripting (XSS) due to insufficient input sanitization and output escaping on the 'drag_n_drop_text' and 'drag_n_drop_browse_text' settings. An authenticated attacker with administrator-level privileges can inject arbitrary web scripts into these fields. These scripts are then stored and executed in the context of any user's browser who visits the affected pages. While the attack requires high privileges, the impact is elevated because the script can execute in the context of other users (Scope: Changed). A patch appears to be available in versions following 1.3.9.7.
