Django REST framework: TokenProxy.delete() reports success and revokes nothing
影響: pip:djangorestframework >= 3.12.0, < 3.18.2 → 3.18.2 Deleting an authentication token through TokenProxy silently deletes nothing. The call raises no exception and reports success, the database row survives, and the token keeps authenticating. Any application, admin integration or operational script that revokes credentials by calling .delete() on a TokenProxy instance believes it has revoked a token that is still live. Details TokenProxy overrides pk to return the user id (rest_framework/authtoken/models.py:49-63): python @property def pk(self):…
Django REST framework: Accept header with many large quoted parameters burns ~19s of CPU per request in content negotiation
影響: pip:djangorestframework < 3.18.2 → 3.18.2 DRF's content negotiation parses each Accept token several times per request and never limits the number of tokens or their total size. Each parse ends up in Django's parse_header_parameters, which takes quadratic time when a quoted parameter value is packed with semicolons. On my machine a single GET with a 780KB Accept header made of 96 such tokens kept one gunicorn worker busy for 18.87 seconds (Django 6.1, djangorestframework 3.18.0, gunicorn 26.0.0, Python 3.13, Docker on macOS). The heade…
Django REST framework: JSONParser applies an attacker-named codec to the request stream
影響: pip:djangorestframework >= 3.6.4, < 3.18.2 → 3.18.2 An unauthenticated attacker can defeat Django's DATA_UPLOAD_MAX_MEMORY_SIZE limit and force a worker process to allocate arbitrary memory, by naming a compression codec in the Content-Type charset parameter. A 108-byte request body produces a 50,331,648-character value inside the view, an amplification factor of 466,033, and grows process peak RSS by about 97 MiB. No application configuration is required beyond DRF's default parser set; the endpoint only has to accept a JSON body. Details JSONP…
