{"id":"CVE-2026-41649","state":"PUBLISHED","title":"Outline has IDOR in document share creation that allows unauthorized access to private documents across workspaces","description":"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.","publishedAt":"2026-04-28T20:11:28.283Z","updatedAt":"2026-04-29T13:12:25.759Z","severity":{"score":7.7,"label":"High","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:N","source":"GitHub_M"},"assigner":"GitHub_M","products":["outline outline"],"affected":[{"vendor":"outline","product":"outline","versions":[{"version":">= 0.86.0, < 1.7.0","status":"affected"}]}],"references":["https://github.com/outline/outline/security/advisories/GHSA-23jj-rp48-w7q7","https://github.com/outline/outline/commit/1b91a295e10f58a1088c54f533773788325ff460","https://github.com/outline/outline/releases/tag/v1.7.0"],"weaknesses":["CWE-639"],"ingestedAt":"2026-10-29T20:11:57.932Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/41xxx/CVE-2026-41649.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-41649","state":"PUBLISHED","datePublished":"2026-04-28T20:11:28.283Z","dateUpdated":"2026-04-29T13:12:25.759Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-04-21T23:58:43.802Z"},"containers":{"cna":{"title":"Outline has IDOR in document share creation that allows unauthorized access to private documents across workspaces","descriptions":[{"lang":"en","value":"Outline is a service that allows for collaborative documentation.
