Hi,

The following vulnerability was published for python-jwcrypto.

CVE-2024-28102[0]:
| JWCrypto implements JWK, JWS, and JWE specifications using python-
| cryptography. Prior to version 1.5.6, an attacker can cause a denial
| of service attack by passing in a malicious JWE Token with a high
| compression ratio. When the server processes this token, it will
| consume a lot of memory and processing time. Version 1.5.6 fixes
| this vulnerability by limiting the maximum token length.


If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
