Aiohttp

AIOHTTP is an asynchronous HTTP client/server framework for asyncio and Python. In versions 3.13.2 and below, reading multiple invalid cookies can lead to a logging storm. [CVSS 5.3 MEDIUM]

AIOHTTP is an asynchronous HTTP client/server framework for asyncio and Python. In versions 3.13.2 and below, handling of chunked messages can result in excessive blocking CPU usage when receiving a large number of chunks. [CVSS 5.3 MEDIUM]

AIOHTTP is an asynchronous HTTP client/server framework for asyncio and Python. Versions 3.13.2 and below allow a request to be crafted in such a way that an AIOHTTP server's memory fills up uncontrollably during processing. [CVSS 7.5 HIGH]

AIOHTTP is an asynchronous HTTP client/server framework for asyncio and Python. Versions 3.13.2 and below allow for an infinite loop to occur when assert statements are bypassed, resulting in a DoS attack when processing a POST body. [CVSS 7.5 HIGH]

AIOHTTP is an asynchronous HTTP client/server framework for asyncio and Python. Versions 3.13.2 and below contain parser logic which allows non-ASCII decimals to be present in the Range header. [CVSS 5.3 MEDIUM]

AIOHTTP is an asynchronous HTTP client/server framework for asyncio and Python. Versions 3.13.2 and below enable an attacker to ascertain the existence of absolute path components through the path normalization logic for static files meant to prevent path traversal. [CVSS 5.3 MEDIUM]

AIOHTTP is an asynchronous HTTP client/server framework for asyncio and Python. Versions 3.13.2 and below of the Python HTTP parser may allow a request smuggling attack with the presence of non-ASCII characters. [CVSS 6.5 MEDIUM]

AIOHTTP is an asynchronous HTTP client/server framework for asyncio and Python. Versions 3.13.2 and below allow a zip bomb to be used to execute a DoS against the AIOHTTP server. [CVSS 7.5 HIGH]

AIOHTTP versions prior to 3.12.14 contain a request smuggling vulnerability in the Python parser that fails to properly parse HTTP trailer sections, allowing attackers to bypass firewalls and proxy protections when the pure Python implementation is used. This vulnerability affects deployments running AIOHTTP without C extensions or with AIOHTTP_NO_EXTENSIONS enabled, enabling HTTP request smuggling attacks with high integrity impact. The vulnerability has a CVSS score of 7.5 (High) and is unauthenticated, network-accessible, and requires no user interaction.
