CVE-2024-28102 — JWCrypto vulnerable to JWT bomb Attack in `deserialize` function

2026-09-28T20:24:34.972977+00:00

Affected: latchset jwcrypto

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.
