Allocation of Resources Without Limits or Throttling

Overview Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling in the request.read method. An attacker can cause the server to consume excessive CPU resources by sending a large number of chunked messages. Details Denial of Service DoS describes ...

GHSA-6JHG-HG63-JVVF AIOHTTP vulnerable to denial of service through large payloads

Summary A request can be crafted in such a way that an aiohttp server's memory fills up uncontrollably during processing. Impact If an application includes a handler that uses the Request.post method, an attacker may be able to freeze the server by exhausting the memory. ----- Patch:...
