NewCVE-2026-114136 (opens in a new tab)How to fix?
Upgrade djangorestframework to version 3.18.2 or higher.
Overview
djangorestframework is a powerful and flexible toolkit for building Web APIs.
Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling via JSONParser (and FormParser/MultiPartParser) in rest_framework/parsers.py, which passes the client-supplied charset from the Content-Type header directly to codecs.getreader() without validating that it is a text encoding. Because codecs.getreader() does not consult CodecInfo._is_text_encoding, a client can supply a byte-transform codec such as bz2_codec, causing the request body to be decompressed after Django's DATA_UPLOAD_MAX_MEMORY_SIZE check has already been applied against the compressed wire bytes. A 108-byte compressed payload can expand to over 50 million characters and approximately 97 MiB of peak RSS, exhausting server memory. Additionally, supplying certain byte-transform charsets with an invalid body raises uncaught OSError, TypeError, or LookupError exceptions, crashing the worker process with an unauthenticated HTTP 500 response.
