CVE-2026-59262
AFFiNE's histories GraphQL field fails to validate Doc.Read permission before exposing document edit history, allowing authenticated workspace members to retrieve restricted content timelines.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.41%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
