CVE-2026-45777Network attack vector

Unauthenticated command execution via unsanitized report title

Published Jun 5, 2026 · Updated Jun 5, 2026

OS command injection in Open XDMoD 9.5.0 through 11.0.2 allows remote attackers to execute commands through a crafted report title. The controllers/user_interface.php report path passes the title parameter into PDF generation without neutralizing shell metacharacters. No authentication or user interaction is required; commands run as the web-server process and can read or modify application data, alter configuration, or interrupt service.
