FKIE_CVE-2025-4392

Vulnerability from fkie_nvd - Published: 2025-06-03 10:15 - Updated: 2026-06-17 09:33
Severity
7.2 (High) - CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:L/A:N
Summary
The Shared Files – Frontend File Upload Form & Secure File Sharing plugin for WordPress is vulnerable to Stored Cross-Site Scripting via html File uploads in all versions up to, and including, 1.7.48 due to insufficient input sanitization and output escaping within the sanitize_file() function. This makes it possible for unauthenticated attackers to bypass the plugin’s MIME-only checks and inject arbitrary web scripts in pages that will execute whenever a user accesses the html file.
