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."}], "lastModified": "2026-05-01T15:54:05.830", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:getoutline:outline:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "29EA0359-AC70-427C-A8E3-1367699EF11B", "versionEndExcluding": "1.7.0", "versionStartIncluding": "0.86.0"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
