CVE编号
CVE-2018-7536利用情况
暂无补丁情况
官方补丁披露时间
2018-03-10漏洞描述
在django2.0.3、1.11.11之前和1.8.19之前发现了一个问题。由于两个正则表达式（对于dhango1.8.x，只有一个正则表达式）中的catastrophic backtracking 漏洞，django.utils.html.urlize()函数评估某些输入的速度极慢。urlize()函数用于实现urlize和urlizetrunc template filters，因此是易受攻击的。 解决建议
目前厂商已发布升级补丁以修复漏洞，补丁获取链接:https://www.djangoproject.com/weblog/2018/mar/06/security-releases/受影响软件情况
