CVE-2025-70457Public exploitNetwork attack vector

Unauthenticated code execution via MIME-spoofed PHP upload

Published Jan 23, 2026 · Updated Jan 23, 2026

Unrestricted file upload in Sourcecodester Modern Image Gallery App 1.0 allows remote attackers to execute code through gallery/upload.php. The handler trusts the client-supplied Content-Type, retains a .php extension, and writes the upload into the web-accessible images directory. No authentication or user interaction is required; requesting the saved PHP file executes commands with the web server process's privileges.
