Overview
Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling in the NonBlockingUtf8JsonParserBase file. An attacker can exhaust system memory by streaming JSON input in small chunks to the asynchronous parser, causing unbounded accumulation of digit characters in memory due to missing validation of number length during chunked parsing. This can lead to denial of service by overwhelming the application's memory resources.
