AI-suggested
Red Hat has released updated python-urllib3 packages for Red Hat Enterprise Linux 9.6 Extended Update Support that address these vulnerabilities.

Description
Two security vulnerabilities were addressed in the python-urllib3 package for Red Hat Enterprise Linux 9.6 Extended Update Support. The first is a denial of service vulnerability caused by excessive HTTP response decompression (CVE-2026-44432). The second is an information disclosure vulnerability due to cross-origin redirects forwarding sensitive headers (CVE-2026-44431). These issues have been fixed in updated package versions provided by Red Hat.
