Description
Description
An issue was discovered in 6.0 before 6.0.4, 5.2 before 5.2.13, and 4.2 before 4.2.30.
ASGI requests with a missing or understated `Content-Length` header could
bypass the `DATA_UPLOAD_MAX_MEMORY_SIZE` limit when reading
`HttpRequest.body`, allowing remote attackers to load an unbounded request body into
memory.
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 Superior for reporting this issue.
