External ids are generated uuid v4s (`uuid.New()` in Go), so exploitation requires prior knowledge of a target task UUID through an out-of-band channel. Thus, while the following environments are impacted, there is an extremely low probability it would be exploited.\n\n### Who is impacted. Any Hatchet deployment that hosts more than one tenant on the same instance:\n\n* Hatchet Cloud (multi-tenant SaaS)\n* Self-hosted Hatchet with multiple internal teams / business units sharing one instance\n* Any deployment where a single tenant's API token can be obtained by an attacker\n\nSingle-tenant self-hosted deployments are unaffected in practice (the \"victim\" and \"attacker\" tenants would be the same).","public_affected_ranges":["< 0.106.1"]}],"null_published_at":"2026-11-01T07:29:12.917Z","source_updated_at":"2026-09-22T20:40:48.000Z","source_disclosed_at":"2026-09-22T20:40:46.000Z","is_synthetic_fixture":false,"null_last_reviewed_at":null,"public_change_summary":"First indexed by Null; source disclosure date is shown separately.","null_first_observed_at":"2026-11-01T07:25:10.521Z"}],"next_cursor":null,"snapshot_revision":"42594"}
