CVE-2024-33664
python-jose through 3.3.0 allows attackers to cause a denial of service (resource consumption) during a decode via a crafted JSON Web Encryption (JWE) token with a high compression ratio, aka a "JWT bomb." This is similar to CVE-2024-21319.

Does this matter?
Lower severity and a low EPSS score (0.78%). Track it; it rarely justifies an emergency change on its own.
