Security Fix(es): AIOHTTP is an asynchronous HTTP client/server framework for asyncio and Python. Versions 3.13.2 and below contain parser logic which allows non-ASCII decimals to be present in the Range header. There is no known impact, but there is the possibility that there's a method to exploit a request smuggling vulnerability. This issue is fixed in version 3.13.3.(CVE-2025-69225) aiohttp contains a denial-of-service vulnerability when bypassing asserts, allowing attackers to bypass assertion checks through specific methods leading to service unavailability.(CVE-2025-69227) aiohttp contains a vulnerability when processing large payloads. An attacker can craft large requests to exhaust server resources, leading to denial of service.(CVE-2025-69228) aiohttp is an asynchronous HTTP client/server framework for asyncio and Python. In versions 3.13.2 and below, handling of chunked messages can result in excessive blocking CPU usage when receiving a large number of small chunks. If an application makes use of the `request.read()` method in an endpoint, it may be possible for an attacker to cause the server to spend a moderate amount of blocking CPU time (e.g., 1 second) while processing the request. This could potentially lead to a Denial of Service (DoS) as the server would be unable to handle other requests during that time.(CVE-2025-69229) An update for python-aiohttp is now available for master/openEuler-20.03-LTS-SP4/openEuler-22.03-LTS-SP3/openEuler-22.03-LTS-SP4/openEuler-24.03-LTS/openEuler-24.03-LTS-Next/openEuler-24.03-LTS-SP1/openEuler-24.03-LTS-SP2/openEuler-24.03-LTS-SP3. openEuler Security has rated this update as having a security impact of medium.
