PYSEC-2026-2107

Quick fix

PYSEC-2026-2107 — aiohttp: upgrade to the fixed version with the command below.

pip install --upgrade 'aiohttp>=3.14.1'

Details

AIOHTTP is an asynchronous HTTP client/server framework for asyncio and Python. Prior to 3.14.1, no limit was present on the number of pipelined requests that could be queued. An attacker may be able to use pipelined requests to use excessive amounts of memory, potentially leading to DoS. This vulnerability is fixed in 3.14.1.
