Description

A flaw was found in AIOHTTP, an asynchronous HTTP client/server framework for asyncio and Python. When AIOHTTP follows redirects to a different origin, it incorrectly retains sensitive Cookie and Proxy-Authorization headers. This oversight could lead to information disclosure, where these headers are sent to unintended third-party sites, potentially exposing user session data or authentication credentials.
