CVE-2026-85619
AppFlowy-Cloud 0.9.64 fails to verify that requested collab objects belong to the workspace in authorization checks, allowing attackers to access documents and database rows across workspaces.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.57%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
