{"id":"AZL-89333","summary":"CVE-2026-47265 affecting package python-aiohttp 3.6.2-3","details":"AIOHTTP is an asynchronous HTTP client/server framework for asyncio and Python. Prior to version 3.14.0, cookies set with the `cookies` parameter on requests are sent after following a cross-origin redirect. If a developer uses the `cookies` parameter on a per-request basis then sensitive data might be leaked to an attacker if they manage to control a redirect. Version 3.14.0 patches the issue. If unable to upgrade, using a `Cookie` header in the `headers` parameter is not vulnerable.","modified":"2026-08-30T05:24:52Z","published":"2026-06-02T20:16:37Z","upstream":["CVE-2026-47265"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-47265"}],"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-89333.json"}}],"schema_version":"1.9.0"}
