[scarthgap,1/2] python3-urllib3: fix CVE-2025-50181

From: Yogita Urade <yogita.urade@windriver.com>

urllib3 is a user-friendly HTTP client library for Python. Prior to
2.5.0, it is possible to disable redirects for all requests by
instantiating a PoolManager and specifying retries in a way that
disable redirects. By default, requests and botocore users are not
affected. An application attempting to mitigate SSRF or open redirect
vulnerabilities by disabling redirects at the PoolManager level will
remain vulnerable. This issue has been patched in version 2.5.0.

Steve,

I see in patchwork that this patch has been also rejected, along with
its pair in the series.

If this was because of my remark about CVE-2025-50182, then I would like
to mention that my comment was only about the second patch, and I think
that this one, for CVE-2025-50181, looks correct and useful.

Thanks

Thanks for the clarification.  I'll add this patch to my test queue.
