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)\n\naiohttp 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)\n\naiohttp 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)\n\naiohttp 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)","affected":[{"package":{"ecosystem":"openEuler:24.03-LTS-SP1","name":"python-aiohttp","purl":"pkg:rpm/openEuler/python-aiohttp&distro=openEuler-24.03-LTS-SP1"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.9.3-9.oe2403sp1"}]}],"ecosystem_specific":{"aarch64":["python-aiohttp-debuginfo-3.9.3-9.oe2403sp1.aarch64.rpm","python-aiohttp-debugsource-3.9.3-9.oe2403sp1.aarch64.rpm","python-aiohttp-help-3.9.3-9.oe2403sp1.aarch64.rpm","python3-aiohttp-3.9.3-9.oe2403sp1.aarch64.rpm"],"src":["python-aiohttp-3.9.3-9.oe2403sp1.src.rpm"],"x86_64":["python-aiohttp-debuginfo-3.9.3-9.oe2403sp1.x86_64.rpm","python-aiohttp-debugsource-3.9.3-9.oe2403sp1.x86_64.rpm","python-aiohttp-help-3.9.3-9.oe2403sp1.x86_64.rpm","python3-aiohttp-3.9.3-9.oe2403sp1.x86_64.rpm"]}},{"package":{"ecosystem":"openEuler:24.03-LTS-SP2","name":"python-aiohttp","purl":"pkg:rpm/openEuler/python-aiohttp&distro=openEuler-24.03-LTS-SP2"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.9.3-9.oe2403sp2"}]}],"ecosystem_specific":{"aarch64":["python-aiohttp-debuginfo-3.9.3-9.oe2403sp2.aarch64.rpm","python-aiohttp-debugsource-3.9.3-9.oe2403sp2.aarch64.rpm","python-aiohttp-help-3.9.3-9.oe2403sp2.aarch64.rpm","python3-aiohttp-3.9.3-9.oe2403sp2.aarch64.rpm"],"src":["python-aiohttp-3.9.3-9.oe2403sp2.src.rpm"],"x86_64":["python-aiohttp-debuginfo-3.9.3-9.oe2403sp2.x86_64.rpm","python-aiohttp-debugsource-3.9.3-9.oe2403sp2.x86_64.rpm","python-aiohttp-help-3.9.3-9.oe2403sp2.x86_64.rpm","python3-aiohttp-3.9.3-9.oe2403sp2.x86_64.rpm"]}},{"package":{"ecosystem":"openEuler:24.03-LTS-SP3","name":"python-aiohttp","purl":"pkg:rpm/openEuler/python-aiohttp&distro=openEuler-24.03-LTS-SP3"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.9.3-9.oe2403sp3"}]}],"ecosystem_specific":{"aarch64":["python-aiohttp-debuginfo-3.9.3-9.oe2403sp3.aarch64.rpm","python-aiohttp-debugsource-3.9.3-9.oe2403sp3.aarch64.rpm","python-aiohttp-help-3.9.3-9.oe2403sp3.aarch64.rpm","python3-aiohttp-3.9.3-9.oe2403sp3.aarch64.rpm"],"src":["python-aiohttp-3.9.3-9.oe2403sp3.src.rpm"],"x86_64":["python-aiohttp-debuginfo-3.9.3-9.oe2403sp3.x86_64.rpm","python-aiohttp-debugsource-3.9.3-9.oe2403sp3.x86_64.rpm","python-aiohttp-help-3.9.3-9.oe2403sp3.x86_64.rpm","python3-aiohttp-3.9.3-9.oe2403sp3.x86_64.rpm"]}},{"package":{"ecosystem":"openEuler:20.03-LTS-SP4","name":"python-aiohttp","purl":"pkg:rpm/openEuler/python-aiohttp&distro=openEuler-20.03-LTS-SP4"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.7.4-6.oe2003sp4"}]}],"ecosystem_specific":{"aarch64":["python-aiohttp-debuginfo-3.7.4-6.oe2003sp4.aarch64.rpm","python-aiohttp-debugsource-3.7.4-6.oe2003sp4.aarch64.rpm","python-aiohttp-help-3.7.4-6.oe2003sp4.aarch64.rpm","python3-aiohttp-3.7.4-6.oe2003sp4.aarch64.rpm"],"src":["python-aiohttp-3.7.4-6.oe2003sp4.src.rpm"],"x86_64":["python-aiohttp-debuginfo-3.7.4-6.oe2003sp4.x86_64.rpm","python-aiohttp-debugsource-3.7.4-6.oe2003sp4.x86_64.rpm","python-aiohttp-help-3.7.4-6.oe2003sp4.x86_64.rpm","python3-aiohttp-3.7.4-6.oe2003sp4.x86_64.rpm"]}},{"package":{"ecosystem":"openEuler:22.03-LTS-SP4","name":"python-aiohttp","purl":"pkg:rpm/openEuler/python-aiohttp&distro=openEuler-22.03-LTS-SP4"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.7.4-7.oe2203sp4"}]}],"ecosystem_specific":{"aarch64":["python-aiohttp-debuginfo-3.7.4-7.oe2203sp4.aarch64.rpm","python-aiohttp-debugsource-3.7.4-7.oe2203sp4.aarch64.rpm","python-aiohttp-help-3.7.4-7.oe2203sp4.aarch64.rpm","python3-aiohttp-3.7.4-7.oe2203sp4.aarch64.rpm"],"src":["python-aiohttp-3.7.4-7.oe2203sp4.src.rpm"],"x86_64":["python-aiohttp-debuginfo-3.7.4-7.oe2203sp4.x86_64.rpm","python-aiohttp-debugsource-3.7.4-7.oe2203sp4.x86_64.rpm","python-aiohttp-help-3.7.4-7.oe2203sp4.x86_64.rpm","python3-aiohttp-3.7.4-7.oe2203sp4.x86_64.rpm"]}},{"package":{"ecosystem":"openEuler:24.03-LTS","name":"python-aiohttp","purl":"pkg:rpm/openEuler/python-aiohttp&distro=openEuler-24.03-LTS"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.9.3-9.oe2403"}]}],"ecosystem_specific":{"aarch64":["python-aiohttp-debuginfo-3.9.3-9.oe2403sp1.aarch64.rpm","python-aiohttp-debugsource-3.9.3-9.oe2403sp1.aarch64.rpm","python-aiohttp-help-3.9.3-9.oe2403sp1.aarch64.rpm","python3-aiohttp-3.9.3-9.oe2403sp1.aarch64.rpm","python-aiohttp-debuginfo-3.9.3-9.oe2403sp2.aarch64.rpm","python-aiohttp-debugsource-3.9.3-9.oe2403sp2.aarch64.rpm","python-aiohttp-help-3.9.3-9.oe2403sp2.aarch64.rpm","python3-aiohttp-3.9.3-9.oe2403sp2.aarch64.rpm","python-aiohttp-debuginfo-3.9.3-9.oe2403sp3.aarch64.rpm","python-aiohttp-debugsource-3.9.3-9.oe2403sp3.aarch64.rpm","python-aiohttp-help-3.9.3-9.oe2403sp3.aarch64.rpm","python3-aiohttp-3.9.3-9.oe2403sp3.aarch64.rpm","python-aiohttp-debuginfo-3.9.3-9.oe2403.aarch64.rpm","python-aiohttp-debugsource-3.9.3-9.oe2403.aarch64.rpm","python-aiohttp-help-3.9.3-9.oe2403.aarch64.rpm","python3-aiohttp-3.9.3-9.oe2403.aarch64.rpm"],"src":["python-aioht
