Short explanation
The JSONParser component in Django REST framework uses the client-supplied Content-Type charset value with codecs.getreader without proper validation. A remote unauthenticated attacker can send a compressed request body to consume substantial per-worker memory.
This vulnerability can be exploited remotely without authentication, causing excessive memory consumption and leading to potential denial of service conditions.
What should be done?
- Follow vendor advisories and updates
- Check official releases for patching guidance
Chain of evidence and sources
Django REST framework sürümlerinde JSONParser, istemci tarafından sağlanan charset değerini codecs.getreader ile işler.
Saldırganlar sıkıştırılmış istek gövdesi kullanarak küçük isteklerle yüksek bellek tüketimine neden olabilir.
Show the technical text from the sources
Django REST framework is a toolkit for building Web APIs. From 3.6.4 until 3.18.2, JSONParser.parse in rest_framework/parsers.py uses the client-supplied Content-Type charset value with codecs.getreader, which accepts byte-transform codecs such as bz2_codec rather than only text encodings. A remote unauthenticated client can therefore cause a compressed JSON request body to be expanded after Django has enforced DATA_UPLOAD_MAX_MEMORY_SIZE against only the wire bytes, allowing a very small request to consume substantial per-worker memory. The default parser set is sufficient, and any reachable endpoint that accepts a JSON body is affected. This issue is fixed in version 3.18.2.
