A fixed version on one release line is not the upgrade target for every line. Check your exact version and any vendor backports.
Description
The auth0/java-jwt library may terminate a thread if it receives a JWT with a timestamp claim (exp, nbf, iat) containing an out-of-range value. The condition occurs during token parsing, prior to signature verification. Repeated requests of this nature may lead to degraded availability of the affected service.
