HTTP Request Smuggling

Overview Affected versions of this package are vulnerable to HTTP Request Smuggling in the WebSocket upgrade. An attacker can bypass request boundaries and interfere with HTTP request processing by crafting specially constructed HTTP requests. Remediation Upgrade aiohttp to version 3.14.2 or...

CVE-2026-69243

Affected software: AIOHTTP (async HTTP client/server for asyncio and Python). Vulnerability: HTTP request smuggling in the server-side WebSocket upgrade path due to the HTTP parser handling a WebSocket upgrade request with a body in a way that may allow trailing bytes to be misinterpreted as upgr...

AIOHTTP: WebSocket client accepts compressed frames without negotiated permessage-deflate

Summary The client accepts and decompresses frames with the RSV1 bit set even when the permessage-deflate extension was not negotiated. Impact A client may unexpectedly decompress WebSocket frames when explicitly opted out. This could lead to additional CPU/memory consumption, but is unlikely to ...

Allocation of Resources Without Limits or Throttling

Overview Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling via the WebSocket client. An attacker can cause unexpected decompression of WebSocket frames by sending frames with the RSV1 bit set without proper negotiation, potentially leading to...
