Описание
AIOHTTP is an asynchronous HTTP client/server framework for asyncio and Python. Prior to 3.14.4, the pure Python parser accepts ambiguous HTTP request framing. An unauthenticated attacker can consequently smuggle requests when an application uses AIOHTTP_NO_EXTENSIONS or otherwise runs without a standard wheel and an intermediary interprets the framing differently. This issue is fixed in version 3.14.4.
A flaw was found in aiohttp. When running with the pure Python parser instead of compiled extensions, the parser accepts ambiguous HTTP (Hypertext Transfer Protocol) request framing. An unauthenticated remote attacker could exploit this flaw by sending specially crafted requests through an intermediary proxy that interprets message boundaries differently, resulting in HTTP request smuggling. This may allow an attacker to bypass security controls, poison web caches, or manipulate requests from other users.
Отчет
This vulnerability is rated as Moderate severity because successful exploitation requires specific non-default configurations—specifically forcing the fallback pure-Python parser—alongside an upstream proxy that processes HTTP framing inconsistently. In standard Red Hat product deployments, aiohttp utilizes compiled native C extensions by default, which are not subject to this parsing flaw. Consequently, exploitation is restricted to environments where the C parser is explicitly disabled or unavailable, limiting the practical blast radius.
