WordPress administrators and security teams should verify and update the plugin, restrict file uploads, and monitor for suspicious activity.

• Potential for unauthenticated attackers to upload malicious .phar or .svg files.
• Possible remote code execution on the server via direct file access if .phar files are executed as PHP.
• Potential for Stored Cross-Site Scripting under certain circumstances with .svg file uploads.

Technical summary

The Drag and Drop Multiple File Upload – Contact Form 7 plugin for WordPress is vulnerable to limited upload of files with a dangerous type in all versions up to, and including, 1.3.9.2. This is due to the plugin not blocking .phar and .svg files. The vulnerability allows unauthenticated attackers to upload arbitrary .phar or .svg files containing malicious PHP or JavaScript code.
