{"id":"CVE-2021-39224","details":"Nextcloud is an open-source, self-hosted productivity platform. The Nextcloud OfficeOnline application prior to version 1.1.1 returned verbatim exception messages to the user. This could result in a full path disclosure on shared files. (e.g. an attacker could see that the file `shared.txt` is located within `/files/$username/Myfolder/Mysubfolder/shared.txt`). It is recommended that the OfficeOnline application is upgraded to 1.1.1. As a workaround, one may disable the OfficeOnline application in the app settings.","modified":"2026-04-12T01:58:13.606883Z","published":"2021-10-25T22:15:07.577Z","related":["GHSA-56wm-r6jm-3v9h"],"references":[{"type":"ADVISORY","url":"https://github.com/nextcloud/security-advisories/security/advisories/GHSA-56wm-r6jm-3v9h"},{"type":"FIX","url":"https://github.com/nextcloud/officeonline/pull/204"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/nextcloud/officeonline","events":[{"introduced":"0"},{"fixed":"6b92dde15c1816ea856f6d99fb28397c0f147205"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"1.1.1"}],"cpe":"cpe:2.3:a:nextcloud:officeonline:*:*:*:*:*:*:*:*","source":"CPE_FIELD"}}],"versions":["v1.0.0","v1.0.0-alpha1","v1.0.1","v1.0.2","v1.0.3","v1.1.0"],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2021-39224.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N"}]}
