Bumps [urllib3](https://github.com/urllib3/urllib3) from 2.5.0 to 2.6.0. <details> <summary>Release notes</summary> <p><em>Sourced from <a href="https://github.com/urllib3/urllib3/releases">urllib3's releases</a>.</em></p> <blockquote> <h2>2.6.0</h2> <h2>🚀 urllib3 is fundraising for HTTP/2 support</h2> <p><a href="https://sethmlarson.dev/urllib3-is-fundraising-for-http2-support">urllib3 is raising ~$40,000 USD</a> 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 <a href="https://opencollective.com/urllib3">please consider contributing financially</a> to ensure HTTP/2 support is developed sustainably and maintained for the long-haul.</p> <p>Thank you for your support.</p> <h2>Security</h2> <ul> <li>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 <a href="https://github.com/Cycloctane"><code>@Cycloctane</code></a>, 8.9 High, GHSA-2xpw-w6gg-jr37)</li> <li>Fixed a security issue where an attacker could compose an HTTP response with virtually unlimited links in the <code>Content-Encoding</code> 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 <a href="https://github.com/illia-v"><code>@illia-v</code></a>, 8.9 High, GHSA-gm62-xv2j-4w53)</li> </ul> <blockquote> <p>[!IMPORTANT]</p> <ul> <li>If urllib3 is not installed with the optional <code>urllib3[brotli]</code> 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 <code>urllib3[brotli]</code> to install a compatible Brotli package automatically.</li> <li>If you use custom decompressors, please make sure to update them to respect the changed API of <code>urllib3.response.ContentDecoder</code>.</li> </ul> </blockquote> <h2>Features</h2> <ul> <li>Enabled retrieval, deletion, and membership testing in <code>HTTPHeaderDict</code> using bytes keys. (<a href="https://redirect.github.com/urllib3/urllib3/issues/3653">#3653</a>)</li> <li>Added host and port information to string representations of <code>HTTPConnection</code>. (<a href="https://redirect.github.com/urllib3/urllib3/issues/3666">#3666</a>)</li> <li>Added support for Python 3.14 free-threading builds explicitly. (<a href="https://redirect.github.com/urllib3/urllib3/issues/3696">#3696</a>)</li> </ul> <h2>Removals</h2> <ul> <li>Removed the <code>HTTPResponse.getheaders()</code> method in favor of <code>HTTPResponse.headers</code>. Removed the <code>HTTPResponse.getheader(name, default)</code> method in favor of <code>HTTPResponse.headers.get(name, default)</code>. (<a href="https://redirect.github.com/urllib3/urllib3/issues/3622">#3622</a>)</li> </ul> <h2>Bugfixes</h2> <ul> <li>Fixed redirect handling in <code>urllib3.PoolManager</code> when an integer is passed for the retries parameter. (<a href="https://redirect.github.com/urllib3/urllib3/issues/3649">#3649</a>)</li> <li>Fixed <code>HTTPConnectionPool</code> when used in Emscripten with no explicit port. (<a href="https://redirect.github.com/urllib3/urllib3/issues/3664">#3664</a>)</li> <li>Fixed handling of <code>SSLKEYLOGFILE</code> with expandable variables. (<a href="https://redirect.github.com/urllib3/urllib3/issues/3700">#3700</a>)</li> </ul> <h2>Misc</h2> <ul> <li>Changed the <code>zstd</code> extra to install <code>backports.zstd</code> instead of <code>zstandard</code> on Python 3.13 and before. (<a href="https://redirect.github.com/urllib3/urllib3/issues/3693">#3693</a>)</li> <li>Improved the performance of content decoding by optimizing <code>BytesQueueBuffer</code> class. (<a href="https://redirect.github.com/urllib3/urllib3/issues/3710">#3710</a>)</li> <li>Allowed building the urllib3 package with newer setuptools-scm v9.x. (<a href="https://redirect.github.com/urllib3/urllib3/issues/3652">#3652</a>)</li> <li>Ensured successful urllib3 builds by setting Hatchling requirement to ≥ 1.27.0.
