Changelog

Sourced from cryptography's changelog.

46.0.7 - 2026-04-07

* **SECURITY ISSUE**: Fixed an issue where non-contiguous buffers could be
  passed to APIs that accept Python buffers, which could lead to buffer
  overflow. **CVE-2026-39892**
* Updated Windows, macOS, and Linux wheels to be compiled with OpenSSL 3.5.6.
.. _v46-0-6:
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.
