Overview
Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling due to improper validation of the chunk-size field in chunked Transfer-Encoding within the ChunkedDecoder::read_payload function. An attacker can cause unbounded memory allocation and crash the process by sending a negative chunk-size value in the HTTP request.
