AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:L
Network-delivered via form submission (AV:N/AC:L/PR:N), payload fires only when a user views it (UI:R), and execution in the admin's browser crosses a trust boundary into WordPress (S:C) with limited C/I/A.

Unauthenticated Cross Site Scripting (XSS) in Drag and Drop Multiple File Upload - Contact Form 7 <= 1.3.9.7 versions.
AnalysisAI
Unauthenticated reflected/stored cross-site scripting in the WordPress plugin Drag and Drop Multiple File Upload - Contact Form 7 versions 1.3.9.7 and earlier allows remote attackers to inject script that executes in a victim's browser after user interaction, leading to session theft, account takeover, or pivoting against authenticated administrators. No public exploit identified at time of analysis, and the issue is not listed in CISA KEV. CVSS 3.1 base score is 7.1 with a changed scope reflecting impact across the WordPress admin trust boundary.
Technical ContextAI
The vulnerable component is a WordPress plugin developed by Glen Don Mongaya that extends Contact Form 7 to accept drag-and-drop multi-file uploads (CPE cpe:2.3:a:glen_don_mongaya:drag_and_drop_multiple_file_upload_-_contact_form_7). The root cause class is CWE-79 (Improper Neutralization of Input During Web Page Generation), meaning attacker-controlled input is reflected into HTML/JavaScript context without proper output encoding or contextual sanitization. Because Contact Form 7 add-ons typically process form submissions and render filenames or form parameters in the WordPress admin or front-end pages, the injection sink is reachable from an unauthenticated submission path.
RemediationAI
Upstream fix available per the Patchstack advisory; released patched version not independently confirmed from the provided data, so administrators should update the Drag and Drop Multiple File Upload - Contact Form 7 plugin to the latest available version greater than 1.3.9.7 from the WordPress plugin repository and verify the installed version after upgrade (advisory: https://patchstack.com/database/wordpress/plugin/drag-and-drop-multiple-file-upload-contact-form-7/vulnerability/wordpress-drag-and-drop-multiple-file-upload-contact-form-7-plugin-1-3-9-7-cross-site-scripting-xss-vulnerability). If immediate upgrade is not possible, compensating controls include deactivating the plugin on affected sites (trade-off: removes drag-and-drop upload functionality from Contact Form 7 forms), placing a WAF rule in front of WordPress to block requests containing script tags or common XSS payloads in upload-related parameters (trade-off: may produce false positives on legitimate filenames), and restricting which roles can access form-submission review screens to limit administrator exposure to malicious payloads.
