A tiny serialized value can therefore cause large memory allocation in a consuming browser/runtime. This occurs during evaluation of generated code, not in default `parse` sparse-array construction.\n\nYou would only be affected by this if you were serializing very large sparse arrays and then evaluating the results. In the general use case for `uneval` of sending data to the client, the worst that could happen is the browser tab running out of memory.","public_affected_ranges":[">= 1.0.0, <= 5.9.2"]}],"null_published_at":"2026-11-01T07:29:12.925Z","source_updated_at":"2026-10-01T15:17:16.000Z","source_disclosed_at":"2026-10-01T15:17:13.000Z","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":"2026-11-01T07:22:52.960Z"}],"next_cursor":null,"snapshot_revision":"42594"}
