CVE-2025-50857Public exploitNetwork attack vector

Unauthenticated code execution via upload path traversal

Published Feb 26, 2026 · Updated Feb 26, 2026

Path traversal in ZenTaoPMS 18.11 through 21.6.beta allows remote attackers to execute arbitrary code through a crafted file upload. The AI module's control.php upload handler fails to confine an attacker-controlled file path to the intended upload directory. No authentication or user interaction is required, and successful exploitation runs code with the web service's privileges.
