Quick fix
PYSEC-2026-141 — urllib3: upgrade to the fixed version with the command below.
pip install --upgrade 'urllib3>=2.7.0'Details
urllib3 is an HTTP client library for Python. From 1.23 to before 2.7.0, cross-origin redirects followed from the low-level API via ProxyManager.connection_from_url().urlopen(..., assert_same_host=False) still forward these sensitive headers. This vulnerability is fixed in 2.7.0.
