Quick fix

PYSEC-2020-40 — drf-jwt: upgrade to the fixed version with the command below.

pip install --upgrade 'drf-jwt>=1.15.1'

Details

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.
