Allocation of Resources Without Limits or Throttling

CVE-2025-69228

Medium
6.6/10

Summary

AIOHTTP is an asynchronous HTTP client/server framework for asyncio and Python. Versions through 3.13.2 and 4.x through 4.0.0a1 allow a request to be crafted in such a way that an AIOHTTP server's memory fills up uncontrollably during processing. 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.
