CVE-2026-33154

Dynaconf SSTI 漏洞报告 摘要 Dynaconf 由于 @Jinja 解析器中的不安全模板求值，存在服务端模板注入（SSTI）漏洞。当安装了jinja2 包时，Dynaconf 会在无沙箱环境下求值嵌入在配置值中的模板表达式。 如果攻击者能够影响配置源，例如： 环境变量 .env 文件 容器环境配置 CI/CD 密钥 ...他们就可以在主机系统上执行任意操作系统命令 。此外，@Format 解析器允许对象图遍历，这可能会暴露敏感的运行时对象和环境变量。 详细信息 该漏洞的产生是因为 Dynaconf 的字符串解析器缺乏适当的安全边界。 1. @Jinja 解析器 @Jinja...
