CVE-2024-28102 (GCVE-0-2024-28102)

Vulnerability from cvelistv5 – Published: 2024-03-06 21:09 – Updated: 2024-09-09 13:06

Title

JWCrypto vulnerable to JWT bomb Attack in `deserialize` function

Summary

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.

Severity ?

6.8 (Medium)
