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.

在 Kimai 2.53.0 版本之前，Twig 发票模板沙箱未能阻止对敏感的用户方法调用，导致管理员能够调用 getApiToken() 和 getPlainApiToken() 方法。拥有模板创建权限的攻击者可以将这些方法调用嵌入发票模板中，从而在渲染后的发票输出中泄露已哈希的 API 令牌。
