CVE-2023-53893Public exploitNetwork attack vector

Authenticated internal resource enumeration via callback URL

Published Dec 15, 2025 · Updated Dec 15, 2025

Server-side request forgery in Ateme TITAN File 3.9.12.4 allows remote authenticated users to enumerate internal resources. The job callback URL parser accepts an unvalidated destination and makes attacker-directed HTTP, DNS, or file requests. A valid TITAN web token is required; successful requests expose internal files, services, and network reachability through the server.
