Summary
Potential denial-of-service vulnerability in MultiPartParser via base64-encoded file upload
Details

An issue was discovered in 6.0 before 6.0.4, 5.2 before 5.2.13, and 4.2 before 4.2.30. MultiPartParser allows remote attackers to degrade performance by submitting multipart uploads with Content-Transfer-Encoding: base64 including excessive whitespace. Earlier, unsupported Django series (such as 5.0.x, 4.1.x, and 3.2.x) were not evaluated and may also be affected. Django would like to thank Seokchan Yoon for reporting this issue.
