CVE-2026-113404: Uniong WebITR lets attackers run code via crafted data
CVE-2026-113404 · published 15 days ago
Summary
The WebITR application from Uniong allows a signed‑in user to send specially crafted information that the server will decode using a hard‑coded secret key. By doing this, an attacker can cause the server to run any code they choose, potentially compromising the entire system. Install any available updates from Uniong, change the default encryption key, and restrict who can log in to the application.
