An issue was discovered in 6.0 before 6.0.4, 5.2 before 5.2.13, and 4.2 before 4.2.30. `ASGIRequest` allows a remote attacker to spoof headers by exploiting an ambiguous mapping of two header variants (with hyphens or with underscores) to a single version with underscores. 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 Tarek Nakkouch for reporting this issue.
Update Django to 6.0.4; Django to 5.2.13; Django to 4.2.30 if you use the affected versions. Test the change in a non-production environment first.

hol-guard supply-chain scanDjango vulnerable to ASGI header spoofing via underscore/hyphen conflation affects Django (pip), Django (pip), Django (pip). Severity is high.

AI coding agents often install or upgrade packages automatically in pip. A high vulnerability in a dependency can be pulled into a project through a normal install or update without a human reviewing the change, expanding the blast radius from a single package to every agent workspace that depends on it.
