Django Rest Framework jwt allows obtaining new token from notionally invalidated token

  • Disclosed: 15.03.2020
  • Updated: 11.10.2026 12:19

An issue was discovered in drf-jwt 1.15.x before 1.15.1. It allows attackers with access to a notionally invalidated token to obtain a new, working token via the refresh endpoint, because the blacklist protection mechanism is incompatible with the token-refresh feature. NOTE: drf-jwt is a fork of jpadilla/django-rest-framework-jwt, which is unmaintained.
