Source record

Technical description

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.

CVE / CNA vector: CVSS:3.1/AV:N/AC:H/PR:H/UI:N/S:C/C:L/I:L/A:N
