2.6.3

🚀 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.

Changes

• Fixed a security issue where decompression-bomb safeguards of the streaming API were bypassed when HTTP redirects were followed. (CVE-2026-21441 reported by @​D47A, 8.9 High, GHSA-38jv-5279-wg99)
• Started treating Retry-After times greater than 6 hours as 6 hours by default. (urllib3/urllib3#3743)
• Fixed urllib3.connection.VerifiedHTTPSConnection on Emscripten. (urllib3/urllib3#3752)

Thank you for your support.

Changes

• Fixed HTTPResponse.read_chunked() to properly handle leftover data in the decoder's buffer when reading compressed chunked responses. (urllib3/urllib3#3734)

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.

46.0.6 - 2026-03-25

* **SECURITY ISSUE**: Fixed a bug where name constraints were not applied
  to peer names during verification when the leaf certificate contains a
  wildcard DNS SAN. Ordinary X.509 topologies are not affected by this bug,
  including those used by the Web PKI. Credit to **Oleh Konko (1seal)** for
  reporting the issue. **CVE-2026-34073**
.. _v46-0-5:
46.0.5 - 2026-02-10

• An attacker could create a malicious public key that reveals portions of your private key when using certain uncommon elliptic curves (binary curves). This version now includes additional security checks to prevent this attack. This issue only affects binary elliptic curves, which are rarely used in real-world applications. Credit to XlabAI Team of Tencent Xuanwu Lab and Atuin Automated Vulnerability Discovery Engine for reporting the issue. CVE-2026-26007
• Support for SECT* binary elliptic curves is deprecated and will be removed in the next release.

.. v46-0-4:
