CVSS 3.1
6.8 mediumCVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:N/I:N/A:HCVE-2024-28102
Medium (6.8). EPSS 1.0% chance of exploitation in the next 30 days. Fixed in jwcrypto 1.5.6.
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.
