Doc Text:
A flaw was found in auth0/java-jwt. An unauthenticated remote attacker can cause a Denial of Service (DoS) by sending a JSON Web Token (JWT) containing an out-of-range timestamp claim. Because the issue occurs during token parsing before cryptographic signature verification, processing these malformed tokens can terminate execution threads and degrade service availability.

Description OSIDB Bzimport 2026-10-13 21:38:49 UTC
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.
