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.

mdeslaur | On focal and earlier, the python-pip package bundles python-urllib3 binaries when built. After updating python-urllib3, a no-change rebuild of python-pip is required. On jammy and later, python-urllib3 is bundled in the python-pip package and needs to be patched. |
