CVE-2026-41948— Dify v1.14.1 Path Traversal via Plugin Daemon Internal API Access

Quick assessment

Affected
langgenius dify
Exploitation
High exploitation probability; assess promptly
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

dify是LangGenius开源的一个 LLM 应用程序开发平台。 dify 1.14.1及之前版本存在安全漏洞，该漏洞源于路径遍历问题，可能导致认证用户通过利用不充分的URL路径清理来操纵转发到插件守护进程内部REST API的请求。攻击者可以使用任务标识符中未编码的点序列或操纵的文件名参数遍历出授权租户路径，访问内部端点如调试接口。

Vulnerability Title
Dify v1.14.1 Path Traversal via Plugin Daemon Internal API Access
Source: CVE Program / CVE List V5
Vulnerability Description
Dify version 1.14.1 and prior contain a path traversal vulnerability that allows authenticated users to manipulate requests forwarded to the Plugin Daemon's internal REST API by exploiting insufficient URL path sanitization. Attackers can traverse out of their authorized tenant path using unencoded dot sequences in task identifiers or manipulated filename parameters to access internal endpoints such as debug interfaces, requiring only knowledge of the victim tenant's UUID. NOTE: Dify Cloud allows unauthenticated free self-registration, making account creation trivially accessible to any attacker.
