Description: Bumps urllib3 from 2.5.0 to 2.6.0.
Release notes
Sourced from urllib3's releases.
2.6.0
🚀 urllib3 is fundraising for HTTP/2 support
urllib3 is raising ~$40,000 USD to release HTTP/2 support and ensure long-term sustainable maintenance of the project after a sharp decline in financial support. If your company or organization uses Python and would benefit from HTTP/2 support in Requests, pip, cloud SDKs, and thousands of other projects please consider contributing financially to ensure HTTP/2 support is developed sustainably and maintained for the long-haul.
Thank you for your support.
Security
Fixed a security issue where streaming API could improperly handle highly compressed HTTP content ("decompression bombs") leading to excessive resource consumption even when a small amount of data was requested. Reading small chunks of compressed data is safer and much more efficient now. (CVE-2025-66471 reported by @Cycloctane, 8.9 High, GHSA-2xpw-w6gg-jr37)
Fixed a security issue where an attacker could compose an HTTP response with virtually unlimited links in the Content-Encoding header, potentially leading to a denial of service (DoS) attack by exhausting system resources during decoding. The number of allowed chained encodings is now limited to 5. (CVE-2025-66418 reported by @illia-v, 8.9 High, GHSA-gm62-xv2j-4w53)
[!IMPORTANT]
If urllib3 is not installed with the optional urllib3[brotli] extra, but your environment contains a Brotli/brotlicffi/brotlipy package anyway, make sure to upgrade it to at least Brotli 1.2.0 or brotlicffi 1.2.0.0 to benefit from the security fixes and avoid warnings. Prefer using urllib3[brotli] to install a compatible Brotli package automatically.
If you use custom decompressors, please make sure to update them to respect the changed API of urllib3.response.ContentDecoder.
