Background
python-aiohttp is an asynchronous HTTP client/server framework for Python, designed to provide a simple and efficient way to handle HTTP requests and responses. It is widely used for building web applications and services due to its non-blocking architecture and support for asyncio. However, recent vulnerabilities have been discovered that could allow attackers to exploit the framework, leading to serious security risks such as request smuggling and cross-site scripting (XSS).
Vulnerability Detail
Multiple vulnerabilities have been identified in python-aiohttp, including improper parsing of HTTP headers and inadequate validation of inputs. These flaws could allow remote attackers to perform request smuggling, leading to unauthorized access or manipulation of requests. Specific vulnerabilities include CVE-2023-47627, CVE-2023-49081, CVE-2023-49082, CVE-2024-23829, CVE-2024-27306, CVE-2024-30251, and CVE-2024-52304. The impact of these vulnerabilities is particularly severe for users of Ubuntu 18.04 LTS, 20.04 LTS, 22.04 LTS, and 24.04 LTS.
