CVE-2026-35583— Emissary 路径遍历漏洞

Emissary has a Path Traversal via Blacklist Bypass in Configuration API

Emissary is a P2P based data-driven workflow engine. Prior to 8.39.0, the configuration API endpoint (/api/configuration/{name}) validated configuration names using a blacklist approach that checked for \, /, .., and trailing .. This could potentially be bypassed using URL-encoded variants, double-encoding, or Unicode normalization to achieve path traversal and read configuration files outside the intended directory. This vulnerability is fixed in 8.39.0.

对路径名的限制不恰当(路径遍历)

Emissary 路径遍历漏洞

Emissary是National Security Agency开源的一个分布式 P2P 数据驱动工作流框架。 Emissary 8.39.0之前版本存在路径遍历漏洞，该漏洞源于配置API端点使用黑名单方法验证配置名称，可能被URL编码变体、双重编码或Unicode规范化绕过，可能导致路径遍历和读取预期目录外的配置文件。
