Description

USN-5526-1 fixed vulnerabilities in PyJWT. Unfortunately this caused a regression by incrementing the internal package version number on Ubuntu 22.04 LTS. This update fixes the problem.

We apologize for the inconvenience.

Original advisory details:

Aapo Oksman discovered that PyJWT incorrectly handled signatures constructed from SSH public keys. A remote attacker could use this to forge a JWT signature.
