Summary
In AIOHTTP before version 3.14.1, DigestAuthMiddleware can send an authentication response after following a cross-origin redirect. The attack requires an open redirect vulnerability on the target domain, and the attacker only receives the digest, allowing credential extraction only if cryptography is weak or passwords are reused.
Risk Assessment
The risk involves potential interception of authentication digests by an attacker, which could compromise user credentials, especially in environments with weak cryptography or password reuse.
Recommendation
Immediately upgrade AIOHTTP to version 3.14.1 or later, which includes a fix for this vulnerability.
Original NVD description (English source)
AIOHTTP is an asynchronous HTTP client/server framework for asyncio and Python. Prior to 3.14.1, DigestAuthMiddleware can send an authentication response after following a cross-origin redirect. This likely requires an open redirect vulnerability or similar on the target domain for an attacker to be able to execute. Further, the attacker is only receiving the digest, so should only be able to extract the user's credentials if the cryptography is weak or there is some kind of password reuse. This vulnerability is fixed in 3.14.1.
