Changelog

Sourced from cryptography's changelog.

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.
