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.

CVE-2026-53804 is an authenticated OS command injection vulnerability in Centuran Consulting's OTRS Community Edition, specifically in the PGP encryption module. Administrators can supply crafted configuration values for the PGP binary path and command options that are concatenated unsafely into shell commands. This allows arbitrary command execution as the web server user during normal ticket operations after deployment of the malicious configuration. The vulnerability affects versions up to and including 6.0.41. No official patch or remediation guidance is currently provided.

Successful exploitation allows an authenticated administrator to execute arbitrary operating system commands with the privileges of the web server process. This can lead to full system compromise or unauthorized actions on the server hosting OTRS Community Edition. The vulnerability is high severity due to the potential for significant impact on confidentiality, integrity, and availability.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict administrator access to trusted personnel only and review configuration changes carefully to prevent injection of malicious command parameters.
