CVE-2026-5364 Details
Description
The Drag and Drop File Upload for Contact Form 7 plugin for WordPress is vulnerable to arbitrary file upload in versions up to, and including, 1.1.3. This is due to the plugin extracting the file extension before sanitization occurs and allowing the file type parameter to be controlled by the attacker rather than being restricted to administrator-configured values, which when combined with the fact that validation occurs on the unsanitized extension while the file is saved with a sanitized extension, allows special characters like '$' to be stripped during the save process. This makes it possible for unauthenticated attackers to upload arbitrary PHP files and potentially achieve remote code execution, however, an .htaccess file and name randomization is in place which restricts real-world exploitability.
A vulnerability exists in the WordPress plugin 'Drag and Drop File Upload for Contact Form 7', in versions through 1.1.3. The issue allows for unauthenticated arbitrary file uploads. This vulnerability arises because the plugin processes file extensions before applying proper sanitization, and it permits attackers to manipulate the file type parameter. The validation of file types is based on unsanitized extensions, while the files are saved with sanitized extensions, creating a loophole. Exploitation could lead to the upload of malicious PHP files, with the potential for remote code execution. However, an .htaccess file and name randomization currently limit the practical exploitability of this vulnerability.
Users are advised to update the plugin to version 1.1.4 or later, where this vulnerability has been patched.
