Summary

python-jwcrypto security update

Details

Implements JWK, JWS, JWE specifications with python-cryptography

Security Fix(es):

VUL-0: CVE-2022-3102: python-jwcrypto: jwcrypto token substitution can lead to authentication bypass(CVE-2022-3102)

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.(CVE-2024-28102)

Severity

6.8 (Medium)
