Severity: MEDIUM
Package: aiohttp @ 3.14.1
Fixed in: 3.14.2

AIOHTTP is an asynchronous HTTP client/server framework for asyncio and Python. Prior to 3.14.2, the HTTP parsers were vulnerable to a request smuggling attack relating to WebSocket upgrades. If using the server-side component, an attacker may be able to execute a request smuggling vulnerability using an edge case in the WebSocket upgrade procedure. A WebSocket upgrade request with a body could cause the parser to switch protocols before the complete request body was received, leaving trailing b

Duplicate of #586 — filed by the supply-chain scanner against the pre-fix dependency set. The bump landed in 611a1d6 (aiohttp 3.14.3, pyasn1 0.6.4, cryptography 50.0.0; verified installed) with per-CVE exploitability rationale on the original issue. The next scheduled scan runs against the fixed lockfile.
