{"id":"AZL-31108","summary":"CVE-2023-43804 affecting package python-urllib3 for versions less than 1.26.18-1","details":"urllib3 is a user-friendly HTTP client library for Python. urllib3 doesn't treat the `Cookie` HTTP header special or provide any helpers for managing cookies over HTTP, that is the responsibility of the user. However, it is possible for a user to specify a `Cookie` header and unknowingly leak information via HTTP redirects to a different origin if that user doesn't disable redirects explicitly. This issue has been patched in urllib3 version 1.26.17 or 2.0.5.","modified":"2026-04-21T04:26:05.082803Z","published":"2023-10-04T17:15:10Z","upstream":["CVE-2023-43804"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-43804"}],"affected":[{"package":{"name":"python-urllib3","ecosystem":"Azure Linux:2","purl":"pkg:rpm/azure-linux/python-urllib3"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.26.18-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-31108.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N"}]}
