Authenticated PHP code execution via droplet ZIP upload

Published Jan 13, 2026 · Updated Jan 13, 2026

Unrestricted file upload in WBCE CMS 1.5.2 allows remote authenticated users to execute arbitrary PHP through a droplet ZIP. The Droplets admin tool imports a crafted ZIP containing a PHP droplet, which the application runs when an authenticated user embeds it in a page. Access to the administrative Droplets tool is required, and successful exploitation grants the uploaded PHP code the web server process's privileges.
