    "lastseen": "",
    "description": "An issue was discovered in 6.0 before 6.0.2, 5.2 before 5.2.11, and 4.2 before 4.2.28.\n`ASGIRequest` allows a remote attacker to cause a potential denial-of-service via a crafted request with multiple duplicate headers.\nEarlier, unsupported Django series (such as 5.0.x, 4.1.x, and 3.2.x) were not evaluated and may also be affected.\nDjango would like to thank Jiyong Yang for reporting this issue.",
