The vulnerability does not bypass operating system file permissions. On OTRS versions prior to OTRS 7, the effective permissions of the web server process are relevant. Starting with OTRS 7, access is limited by the permissions of the dedicated OTRS user. Files with overly permissive ownership or file system permissions may therefore also be affected.\n\nThe affected functionality may additionally attempt to include controlled files in a support bundle. However, support bundles are sent to a predefined OTRS support address, and direct disclosure of arbitrary files to the attacker has not been demonstrated.\n\nAn attacker therefore requires valid administrative access to exploit the vulnerable functionality. The primary demonstrated impact is the deletion of files outside the intended directory within the effective permissions of the OTRS application process.\n\nThis issue affects OTRS:\n\n  *  7.0.X\n  *  8.0.X\n  *  2023.X\n  *  2024.X\n  *  2025.X\n  *  2026.X before 2026.7.X\n\nPlease note that ((OTRS)) Community Edition 6.x and before are vulnerable. Products based on the ((OTRS)) Community Edition also very likely to be affected","state":0,"publishedAt":"2026-10-12T06:48:56.976+00:00","modifiedAt":"2026-10-15T18:07:51.302+00:00","affected":[{"ecosystem":"Vendor product","name":"OTRS","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"defaultStatus\": \"affected\",\n                    \"modules\": [\n                        \"Admin Interface\"\n                    ],\n                    \"product\": \"OTRS\",\n                    \"vendor\": \"OTRS GmbH (former OTRS AG)\",\n                    \"versions\": [\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"7.0.x\"\n                        },\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"8.0.x\"\n                        },\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"2023.x\"\n                        },\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"2024.x\"\n                        },\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"2025.x\"\n                        },\n                        {\n                            \"lessThanOrEqual\": \"2026.6.x\",\n                            \"status\": \"affected\",\n                            \"version\": \"2026.x\",\n                            \"versionType\": \"patch\"\n                        }\n                    ]\n                }"},{"ecosystem":"Vendor product","name":"((OTRS)) Community Edition","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"defaultStatus\": \"unaffected\",\n                    \"modules\": [\n                        \"Admin Interface\"\n                    ],\n                    \"product\": \"((OTRS)) Community Edition\",\n                    \"vendor\": \"OTRS GmbH (former OTRS AG)\",\n                    \"versions\": [\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"6.x\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:N/I:H/A:H","score":8.7,"severity":"HIGH"}],"references":["https://otrs.com/release-notes/otrs-security-advisory-2026-12/"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-78355","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-78355","identifiers":["CVE-2026-78355"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
