In affected versions, the constructor name in the output is read from a property that data on the value can replace, and it is written without checks. A typed array that received properties from untrusted data can then put arbitrary code into the serialized output.\n\n### Details\n\nVersion 1.6.0 changed how seroval finds the class of an object, so that objects with their own `constructor` property serialize correctly. Typed arrays still took the constructor name from the value itself, so the name could come from the untrusted property instead of the array's real type.\n\nThese functions are affected:\n\n- `serialize`, `serializeAsync`\n- `crossSerialize`, `crossSerializeAsync`, `crossSerializeStream`\n- the `Serializer` class\n- `compileJSON`\n\n`fromJSON` and `fromCrossJSON` are not affected: they only accept the names of the built-in typed arrays. With the `compactArrayBufferViews` option, the same lookup throws a `TypeError` instead of writing code.\n\n### Impact\n\nAn application is affected only when it serializes a typed array that has an own `constructor` property set from untrusted data.
