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."}],"source":{"advisory":"GHSA-23jj-rp48-w7q7","discovery":"UNKNOWN"}},"adp":[{"references":[{"url":"https://github.com/outline/outline/security/advisories/GHSA-23jj-rp48-w7q7","tags":["exploit"]}],"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-04-29T13:11:57.248692Z","id":"CVE-2026-41649","options":[{"Exploitation":"poc"},{"Automatable":"no"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-04-29T13:12:25.759Z"}}]}}
