Description

pyjwt regression 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.
