Default since v1.0.)\n- Or, disable the guest agent (`limactl create --plain`)","public_affected_ranges":["<= 2.1.2"]}],"null_published_at":"2026-11-03T10:03:26.566Z","source_updated_at":"2026-08-14T19:24:34.000Z","source_disclosed_at":"2026-08-14T19:24:33.000Z","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":"2026-11-02T20:15:44.568Z"}],"next_cursor":null,"snapshot_revision":"42594"}
