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.

Grav CMS 2.0.16 版本之前，在未沙箱化的 Twig 渲染中未能对 system、site 和 theme 配置数组进行过滤，攻击者可以读取敏感的配置值。拥有页面内容编辑权限的攻击者可以通过在 Twig 模板中使用点（ ）表示法访问原始配置数组，包括缓存凭据等敏感信息，从而绕过 config_denied_paths 限制。
