Outline · Outline · CVE-2026-41649
**Name of the Vulnerable Software and Affected Versions**
Outline versions 0.86.0 through 1.6.9
**Description**
An insecure direct object reference exists in the 'shares.create' API endpoint. When both `collectionId` and `documentId` are provided in a request, the authorization logic verifies access to the collection but ignores the document. This allows an authenticated attacker to generate a valid public share link for any document on the platform, including those from other workspaces. The full contents of the document can subsequently be retrieved via the 'documents.info' endpoint.
**Recommendations**
Update to version 1.7.0.
