High CVSS 7.2

CVE-2026-53804

NVD analysis in progress

OTRS Community Edition contains an authenticated OS command injection vulnerability in the PGP encryption module that allows administrators to execute arbitrary operating-system commands by supplying crafted values for the PGP binary path and command options. 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.

What this means

Exposure
Exploitable remotely over the network, with a privileged account and with no action from the victim.
Impact
An attacker can read sensitive data, modify or destroy data and take the service offline.
Weakness
Unfiltered input reaches the system shell, letting the attacker run their own commands on the server.
Likelihood
Its EPSS score puts short-term exploitation in a middle band: neither negligible nor imminent.

What to doFold into the next patch cycle.
