High severity, CVSS 7.2. EPSS: 1.5% chance of exploitation in the next 30 days.

Administrator-supplied configuration values are concatenated without sanitization into a shell command, enabling arbitrary command execution as the web server process user during normal ticket operations after the malicious configuration is deployed.
