GHSA-933h-hp56-hf7m Django: SGI requests with a missing or understated `Content-Length` header could bypass the `DATA_UPLOAD_MAX_MEMORY_SIZE` limit

• PyPI Django: >= 6.0, < 6.0.4 → fixed in 6.0.4 • PyPI Django: >= 5.2, < 5.2.13 → fixed in 5.2.13 • PyPI Django: >= 4.2, < 4.2.30 → fixed in 4.2.30

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.
