CVE-2026-54280
AIOHTTP: Payload Response Resources Are Not Closed After Mid-Body Disconnect
Reported by github_m · Published June 22, 2026
aiohttp is fixed in 3.14.1 (PyPI)
AIOHTTP is an asynchronous HTTP client/server framework for asyncio and Python. Prior to 3.14.1, payload resources are not closed correctly when a client disconnects in the middle of a write. If a payload is using an open file or similar limited resource, then an attacker may be able to cause resource starvation temporarily until garbage collection or similar closes the file. This vulnerability is fixed in 3.14.1.
