Exploitation
Public or AI PoC available; prioritize validation
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

在 Kimai 版本低于 2.62.0 的情况下，QuickEntry 控制器在创建新的工时记录时未能正确验证“创建其他人员的工时表”（create_other_timesheet）权限。具备“查看其他人员工时表”（view_other_timesheet）和“编辑其他人员工时表”（edit_other_timesheet）权限的已认证用户，可以通过提交 QuickEntry 表单来创建属于团队其他成员的工时记录，从而绕过系统在其他地方实施的授权检查机制。
