CVE-2026-85186Public exploitNetwork attack vector

Authenticated code execution via polyglot image upload

Published Sep 3, 2026 · Updated Sep 3, 2026

Unrestricted file upload in Online Medicine Delivery System 1.0 allows remote authenticated users to execute code via a crafted avatar. The doupdateimage function in customer/controller.php retains the photo filename, trusts a bypassable getimagesize result, and stores the file in the web-accessible customer_image directory. A customer session is required; a GIF/PHP polyglot passes the image check and executes with the web server's privileges when requested.
