CVE-2025-5746 — Drag and Drop Multiple File Upload (Pro) security vulnerability

Critical CVSS 9.8

The Drag and Drop Multiple File Upload (Pro) - WooCommerce plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in the dnd_upload_cf7_upload_chunks() function in version 5.0 - 5.0.5 (when bundled with the PrintSpace theme) and all versions up to, and including, 1.7.1 (in the standalone version). This makes it possible for unauthenticated attackers to upload arbitrary files on the affected site's server which may make remote code execution possible. The execution of PHP is disabled via a .htaccess file but is still possible in certain server configurations. CVE-2025-49885 may be a duplicate of this.

Matched remediation archetype

Path traversal, unsafe upload, and file handling

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Trace untrusted filenames, archive entries, URLs, and path segments into read, write, include, extraction, and upload operations.
  • Identify filesystem roots, mount permissions, symbolic-link behavior, archive handling, and whether uploaded content is web-accessible or executable.
  • Review canonicalization and containment checks across supported operating systems and storage backends.

Remediate safely

  • Generate server-side storage identifiers and resolve paths beneath a fixed root using filesystem-aware containment checks.
  • Reject absolute, parent-relative, alternate-separator, device, link, and archive entries that escape the intended root.
  • Store uploads outside executable or served paths, validate type and size, and use private atomic temporary files.
