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 proxys 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. DRFs 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.
Weakness
The product detects a specific error, but takes no actions to handle the error.
