CVE-2026-30848— Parse Server: `PagesRouter` path traversal allows reading files outside configured pages directory

Parse Server: `PagesRouter` path traversal allows reading files outside configured pages directory

Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. Prior to versions 8.6.8 and 9.5.0-alpha.8, the PagesRouter static file serving route is vulnerable to a path traversal attack that allows unauthenticated reading of files outside the configured pagesPath directory. The boundary check uses a string prefix comparison without enforcing a directory separator boundary. An attacker can use path traversal sequences to access files in sibling directories whose names share the same prefix as the pages directory (e.g. pages-secret starts with pages). This issue has been patched in versions 8.6.8 and 9.5.0-alpha.8.

N/A

对路径名的限制不恰当(路径遍历)

Parse Server 路径遍历漏洞

Parse Server是Parse Platform开源的一个开源后端，可以部署到任何可以运行 Node.js 的基础设施。 Parse Server 8.6.8之前版本和9.5.0-alpha.8之前版本存在路径遍历漏洞，该漏洞源于路径遍历攻击，可能导致读取配置目录外的文件。
