{"id":"AZL-73512","summary":"CVE-2025-69229 affecting package python-aiohttp 3.6.2-3","details":"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 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 DoS as the server would be unable to handle other requests during that time. This issue is fixed in version 3.13.3.","modified":"2026-04-01T05:22:38.514467Z","published":"2026-01-06T00:15:48Z","upstream":["CVE-2025-69229"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-69229"}],"affected":[{"package":{"name":"python-aiohttp","ecosystem":"Azure Linux:2","purl":"pkg:rpm/azure-linux/python-aiohttp"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"3.6.2-3"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-73512.json"}}],"schema_version":"1.7.5"}
