CVE-2025-34322Public exploitNetwork attack vector

Authenticated command execution via unescaped AI settings

Published Nov 17, 2025 · Updated Nov 17, 2025

Command injection in Nagios Log Server before 2026R1.0.1 allows remote authenticated users to execute commands as www-data. Dashboard::natural_language_to_query() places model, API-key, provider-address, and port settings into a command passed to shell_exec() without argument escaping. Exploitation requires access to Global Settings, enablement of the experimental feature, and a subsequent Natural Language Queries request; successful commands run with the web server account's host access.
