CVE-2026-34515 Details
Description
AIOHTTP is an asynchronous HTTP client/server framework for asyncio and Python. Prior to version 3.13.4, on Windows the static resource handler may expose information about a NTLMv2 remote path. This issue has been patched in version 3.13.4.
A vulnerability exists in AIOHTTP versions prior to 3.13.4, specifically on Windows systems. The static resource handler may inadvertently reveal information about a remote NTLMv2 path. This exposure could potentially allow an attacker to extract NTLMv2 hashes and retrieve user credentials, especially if the application is using AIOHTTP's static resource handler in a production environment.
Users can upgrade to AIOHTTP version 3.13.4 or later to address this vulnerability.
