{"id":"CVE-2026-53804","summary":"OTRS Community Edition OS Command Injection via PGP Configuration","details":"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.","modified":"2026-08-23T03:42:55.488632489Z","published":"2026-08-20T21:13:24.493Z","database_specific":{"cna_assigner":"VulnCheck","cwe_ids":["CWE-78"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/53xxx/CVE-2026-53804.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/53xxx/CVE-2026-53804.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-53804"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/otrs-community-edition-os-command-injection-via-pgp-configuration"},{"type":"PACKAGE","url":"https://github.com/Centuran/OTRS-Community-Edition"},{"type":"EVIDENCE","url":"https://h00die-gr3y.github.io/research/cve-2026-53804/"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/centuran/otrs-community-edition","events":[{"introduced":"0"},{"last_affected":"0a674ad2fa8c61c889e708437432cfb1473c74cf"}],"database_specific":{"source":"AFFECTED_FIELD","extracted_events":[{"introduced":"0"},{"last_affected":"6.0.41"}]}}],"versions":["v6.0.41","v6.0.40","v6.0.39","v6.0.38","v6.0.37","v6.0.33","v6.0.32"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-53804.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N"}]}
