CVE-2026-54273

AIOHTTP is an asynchronous HTTP client/server framework for asyncio and Python. Prior to 3.14.1, no limit was present on the number of pipelined requests that could be queued. An attacker may be able to use pipelined requests to use excessive amounts of memory, potentially leading to DoS. This...

CVE-2026-54280

CVE-2026-54280 affects the AIOHTTP project (async HTTP client/server for asyncio/Python). Before version 3.14.1, payload resources may not be closed correctly if a client disconnects mid-write, allowing temporary resource starvation when a payload uses a limited resource (e.g., open files). The i...
