DescriptionCVE.org

The Drag and Drop Multiple File Upload for Contact Form 7 plugin for WordPress is vulnerable to Stored Cross-Site Scripting via 'drag_n_drop_text' and 'drag_n_drop_browse_text' Settings in all versions up to, and including, 1.3.9.7 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with administrator-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

AnalysisAI

Stored Cross-Site Scripting in the Drag and Drop Multiple File Upload for Contact Form 7 WordPress plugin (all versions through 1.3.9.7) allows authenticated administrators to persist malicious JavaScript via the 'drag_n_drop_text' and 'drag_n_drop_browse_text' plugin settings fields, which subsequently execute in the browsers of any site visitor accessing a page containing an affected CF7 upload form. The CVSS Scope:Changed designation reflects this cross-user impact - a compromised or rogue admin can silently weaponize public-facing forms without further interaction. No public exploit or CISA KEV listing exists at time of analysis, and the CVSS score of 4.4 reflects the high privilege and high complexity prerequisites that substantially limit opportunistic exploitation.

Technical ContextAI

CWE-79 (Improper Neutralization of Input During Web Page Generation) describes this root cause: user-supplied string values stored in plugin settings are neither sanitized on input nor properly escaped on output when rendered in the WordPress front-end. The affected plugin, identified by CPE cpe:2.3:a:glenwpcoder:drag_and_drop_multiple_file_upload_for_contact_form_7, extends Contact Form 7 with drag-and-drop file upload UI components. The vulnerable parameters - 'drag_n_drop_text' and 'drag_n_drop_browse_text' - control UI label text that is rendered directly into page HTML. Reference sources point specifically to dnd-upload-cf7.php (lines 587 and 1445) and codedropz-uploader-min.js (line 15) in both 1.3.9.6 and 1.3.9.7 tags, confirming the flaw is present across at least these two consecutive release versions. The S:C (Scope Changed) CVSS component confirms the injected script escapes the plugin context and affects the victim's browser session.

RemediationAI

An upstream fix is available via WordPress plugin repository changeset 3508522 (https://plugins.trac.wordpress.org/changeset?sfp_email=&sfph_mail=&reponame=&old=3508522%40drag-and-drop-multiple-file-upload-contact-form-7&new=3508522%40drag-and-drop-multiple-file-upload-contact-form-7); however, the exact patched release version number is not independently confirmed from the available data - administrators should update to the latest available version via the WordPress plugin dashboard and verify the installed version exceeds 1.3.9.7. As a compensating control pending update, restrict access to the WordPress admin panel via IP allowlisting to prevent unauthorized or compromised administrators from modifying plugin settings; note this does not eliminate risk from legitimate but malicious insiders. Reviewing existing plugin settings for unexpected content in 'drag_n_drop_text' and 'drag_n_drop_browse_text' fields is recommended to detect prior injection. The Wordfence advisory at https://www.wordfence.com/threat-intel/vulnerabilities/id/01d9b7c1-8f34-4c87-af68-a5e6c698b2d8 should be monitored for confirmed patched version confirmation.
