    "title": "Django REST framework: TokenProxy.delete() reports success and revokes nothing",
    "summary": "Django REST framework is a toolkit for building Web APIs. From 3.12.0 until 3.18.2, TokenProxy.delete() in rest_framework/authtoken/models.py uses the proxy's user-id pk while the concrete Token token-string primary key identifies rows, so Django issues a deletion query that matches no row and reports zero deletions without raising an error. Applications, administrative integrations, or operational scripts that revoke credentials through a TokenProxy instance can therefore believe revocation succeeded while the token remains live and continues authenticating. DRF's own TokenAdmin.delete_model workaround is not affected, but other callers can leave access available indefinitely because DRF tokens do not expire automatically. This issue is fixed in version 3.18.2.",
