Vulnerability Description
In Eclipse Theia versions 1.66.0 and up until including 1.73.1, the `@theia/plugin-ext` backend exposes the `/hostedPlugin/:pluginId/:path(*)` HTTP endpoint, which resolves the requested file path with `path.resolve(localPath, filePath)` without verifying that the resolved path stays within the plugin's directory. An unauthenticated network attacker can send percent-encoded `../` sequences (`%2e%2e%2f`) that decode into the path parameter and escape the plugin directory, allowing arbitrary files readable by the Theia backend process to be retrieved. Plugin IDs are derived deterministically from a plugin's publisher and name, so built-in plugins serve as reliable anchors that require no prior knowledge of the target system.

Vulnerability Title
Eclipse Theia 路径遍历漏洞
Vulnerability Description
Eclipse Theia是美国Eclipse基金会开源的一个可构建云端及桌面集成开发环境的开发框架。 Eclipse Theia 1.66.0版本至1.73.1版本存在路径遍历漏洞,该漏洞源于@theia/plugin-ext后端在通过/hostedPlugin/:pluginId/:path(*)接口解析文件路径时未验证路径是否在插件目录内,未经身份验证的攻击者可通过发送百分号编码的`../`序列(`%2e%2e%2f`)逃离插件目录,导致读取后端进程可访问的任意文件。
