SCA: security update for cryptography (GHSA-m959-cc7f-wv43)

medium Tenable Self-Hosted Container Security Plugin ID 439581

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - cryptography is a package designed to expose cryptographic primitives and recipes to Python developers.
 Prior to version 46.0.6, DNS name constraints were only validated against SANs within child certificates,
 and not the "peer name" presented during each validation. Consequently, cryptography would allow a peer
 named bar.example.com to validate against a wildcard leaf certificate for *.example.com, even if the
 leaf's parent certificate (or upwards) contained an excluded subtree constraint for bar.example.com. This
 issue has been patched in version 46.0.6. (CVE-2026-34073)

Solution

Update the cryptography library and its related packages to version 46.0.6 or later.
