Summary
python-urllib3 security update
Details

HTTP library with thread-safe connection pooling, file post support, sanity friendly, and more.

Security Fix(es):

urllib3 is a user-friendly HTTP client library for Python. Starting in version 1.24 and prior to 2.6.0, the number of links in the decompression chain was unbounded allowing a malicious server to insert a virtually unlimited number of compression steps leading to high CPU usage and massive memory allocation for the decompressed data. This vulnerability is fixed in 2.6.0.(CVE-2025-66418)
