{"id":"AZL-110692","summary":"CVE-2026-111749 affecting package python-aiohttp 3.6.2-3","details":"AIOHTTP is an asynchronous HTTP client/server framework for asyncio and Python. Prior to 3.14.4, Host-Only scope on an existing parent-domain cookie can be removed by a subdomain. A user who accesses an untrusted subdomain can consequently have host-only protections stripped from cookies, although impact is limited when applications do not reflect those cookies to a browser. This issue is fixed in version 3.14.4.","modified":"2026-10-31T05:31:43Z","published":"2026-10-19T17:17:04Z","upstream":["CVE-2026-111749"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-111749"}],"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-110692.json"}}],"schema_version":"1.9.2"}
