Such a user can therefore write attacker-controlled content to any file the Karaf process can write, including files the same ACL otherwise reserves to \"admin\" (etc/users.properties,\u00A0etc/*.acl.*.cfg,\u00A0etc/org.apache.karaf.management.cfg, and similar), allowing a manager-role user to grant themselves the admin role or otherwise take over the container.\n\n\n\n\n\n\nConfigMBeanImpl.install()\u00A0and the\u00A0config:install\u00A0shell command already guarded the equivalent risk on their own code path with a\u00A0finalname.contains(\"..\")\u00A0string check, but that check does not stop absolute paths or symlink-based escapes, and it was never applied to\u00A0ConfigRepositoryImpl.update()\u00A0/\u00A0createFactoryConfiguration()\u00A0at all.","state":0,"publishedAt":"2026-09-29T08:34:11.409+00:00","modifiedAt":"2026-10-01T14:10:47.838+00:00","affected":[{"ecosystem":"Vendor product","name":"org.apache.karaf.config.core.impl","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"Apache Software Foundation\",\n                    \"product\": \"Apache Karaf\",\n                    \"packageName\": \"org.apache.karaf.config.core.impl\",\n                    \"versions\": [\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"0\",\n                            \"lessThan\": \"4.4.12\",\n                            \"versionType\": \"semver\"\n                        }\n                    ],\n                    \"defaultStatus\": \"unaffected\"\n                }"}],"metrics":[],"references":["https://lists.apache.org/thread/op8trtz1qxkdwj2rjozhd9yt2yd6nhw4"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-91012","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-91012","identifiers":["CVE-2026-91012"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
