{"id":"AZL-94553","summary":"CVE-2026-69244 affecting package python-aiohttp 3.6.2-3","details":"AIOHTTP is an asynchronous HTTP client/server framework for asyncio and Python. Prior to 3.14.3, an out-of-bounds heap read could occur in the C response parser while building an error message for a malformed response. An attacker controlled server, or possibly an accidental response, could trigger a DoS in the client. The vulnerable path was error message construction in aiohttp/_http_parser.pyx, where an llhttp error-position pointer was used to build a snippet for malformed chunked responses and malformed request or response bytes at the buffer end. This issue is fixed in version 3.14.3.","modified":"2026-08-30T05:24:52Z","published":"2026-08-03T21:16:42Z","upstream":["CVE-2026-69244"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-69244"}],"affected":[{"package":{"name":"python-aiohttp","ecosystem":"Azure Linux:3","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-94553.json"}}],"schema_version":"1.9.0"}
