The vulnerability is not present in standalone Collabora Online servers; only this deployment with CODE Server is affected.","state":0,"publishedAt":"2026-10-14T02:27:42.315+00:00","modifiedAt":"2026-10-24T03:55:50.462+00:00","affected":[{"ecosystem":"https://apps.nextcloud.com","name":"richdocumentscode","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"collectionURL\": \"https://apps.nextcloud.com\",\n                    \"defaultStatus\": \"affected\",\n                    \"packageName\": \"richdocumentscode\",\n                    \"product\": \"Collabora Online - Built-in CODE Server\",\n                    \"repo\": \"https://github.com/CollaboraOnline/richdocumentscode\",\n                    \"vendor\": \"Collabora\",\n                    \"versions\": [\n                        {\n                            \"lessThan\": \"26.4.303\",\n                            \"status\": \"affected\",\n                            \"version\": \"0\",\n                            \"versionType\": \"semver\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","score":9.2,"severity":"CRITICAL"}],"references":["https://github.com/CollaboraOnline/richdocumentscode/issues/354","https://help.nextcloud.com/t/to-collabora-built-in-user-update-asap/250516"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-110447","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-110447","identifiers":["CVE-2026-110447"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
