{"id":"CVE-2026-41649","summary":"Outline has IDOR in document share creation that allows unauthorized access to private documents across workspaces","details":"Outline is a service that allows for collaborative documentation. The `shares.create` API endpoint starting in version 0.86.0 and prior to version 1.7.0 has an insecure direct object reference.. When both `collectionId` and `documentId` are provided in the request, the authorization logic only checks access to the collection, completely ignoring the document. This allows an authenticated attacker to generate a valid public share link for any document on the platform, including documents belonging to other workspaces. The full document contents can then be retrieved via the `documents.info` endpoint. Version 1.7.0 contains a patch.","aliases":["GHSA-23jj-rp48-w7q7"],"modified":"2026-07-08T08:10:43.359666739Z","published":"2026-04-28T20:11:28.283Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/41xxx/CVE-2026-41649.json","cwe_ids":["CWE-639"],"cna_assigner":"GitHub_M"},"references":[{"type":"WEB","url":"https://github.com/outline/outline/releases/tag/v1.7.0"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/41xxx/CVE-2026-41649.json"},{"type":"ADVISORY","url":"https://github.com/outline/outline/security/advisories/GHSA-23jj-rp48-w7q7"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-41649"},{"type":"FIX","url":"https://github.com/outline/outline/commit/1b91a295e10f58a1088c54f533773788325ff460"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/outline/outline","events":[{"introduced":"5bdabc13a608cd7f4fc897205bab905e957ec918"},{"fixed":"568b4ac074c67c5c58c75637c3a60b41f5bb1e6b"},{"fixed":"1b91a295e10f58a1088c54f533773788325ff460"}],"database_specific":{"cpe":"cpe:2.3:a:getoutline:outline:*:*:*:*:*:*:*:*","extracted_events":[{"introduced":"0.86.0"},{"fixed":"1.7.0"}],"source":["CPE_RANGE","REFERENCES"]}}],"versions":["v1.6.1","v1.6.0","v1.5.0","v1.4.0","v1.2.0","v1.2.0-0","v1.1.0","v1.0.1","v1.0.0","v0.87.4","v0.87.2","v0.87.1","v0.87.0","v0.86.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-41649.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:N"}]}
