CVE-2026-120449
Outline before 1.12.0 Improper Access Control via Public Document Shares
Outline before 1.12.0 contains an improper access control vulnerability that allows unauthenticated users to read unpublished documents because the share loader ignores unpublished status. Attackers holding an existing share link can query shares.info, documents.info, or the /s/ share routes to read withdrawn content, while shares.revoke returns 404 and blocks revocation.
