{"id":"UBUNTU-CVE-2025-50182","details":"urllib3 is a user-friendly HTTP client library for Python. Starting in version 2.2.0 and prior to 2.5.0, urllib3 does not control redirects in browsers and Node.js. urllib3 supports being used in a Pyodide runtime utilizing the JavaScript Fetch API or falling back on XMLHttpRequest. This means Python libraries can be used to make HTTP requests from a browser or Node.js. Additionally, urllib3 provides a mechanism to control redirects, but the retries and redirect parameters are ignored with Pyodide; the runtime itself determines redirect behavior. This issue has been patched in version 2.5.0.","modified":"2026-02-04T03:40:50.619761Z","published":"2025-06-19T02:15:00Z","withdrawn":"2026-01-20T05:33:08Z","related":["USN-7599-1"],"upstream":["CVE-2025-50182"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2025-50182"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2025-50182"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-7599-1"}],"affected":[{"package":{"name":"python-urllib3","ecosystem":"Ubuntu:25.04","purl":"pkg:deb/ubuntu/python-urllib3@2.3.0-2ubuntu0.1?arch=source&distro=plucky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.3.0-2ubuntu0.1"}]}],"versions":["2.0.7-2","2.0.7-2ubuntu0.1","2.3.0-1","2.3.0-2"],"ecosystem_specific":{"availability":"No subscription required","binaries":[{"binary_version":"2.3.0-2ubuntu0.1","binary_name":"python3-urllib3"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2025/UBUNTU-CVE-2025-50182.json"}}],"schema_version":"1.7.3","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:N/A:N"},{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N"},{"type":"Ubuntu","score":"medium"}]}
