Quick assessment

Affected
craftcms cms
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

该漏洞允许任何已认证用户无需提供当前密码或处于提权会话中，即可修改自己的密码。此外，如果攻击者的账户拥有“编辑用户”权限（该权限本不应允许修改他人密码），但缺乏“管理用户”权限（该权限才是修改他人密码所必需的），则攻击者还可以修改其他用户的密码。
