CVE-2026-25152— Backstage 路径遍历漏洞

@backstage/plugin-techdocs-node vulnerable to possible Path Traversal in TechDocs Local Generator

Backstage is an open framework for building developer portals, and @backstage/plugin-techdocs-node provides common node.js functionalities for TechDocs. In versions of @backstage/plugin-techdocs-node prior to 1.13.11 and 1.14.1, a path traversal vulnerability in the TechDocs local generator allows attackers to read arbitrary files from the host filesystem when Backstage is configured with `techdocs.generator.runIn: local`. When processing documentation from untrusted sources, symlinks within the docs directory are followed by MkDocs during the build process. File contents are embedded into generated HTML and exposed to users who can view the documentation. This vulnerability is fixed in` @backstage/plugin-techdocs-node` versions 1.13.11 and 1.14.1. Some workarounds are available. Switch to `runIn: docker` in `app-config.yaml` and/or restrict write access to TechDocs source repositories to trusted users only.

对路径名的限制不恰当(路径遍历)

Backstage 路径遍历漏洞

Backstage是Backstage开源的一个应用软件。后台是一个开放的平台,用于构建开发者门户。 Backstage 1.13.11之前版本和1.14.1之前版本存在路径遍历漏洞，该漏洞源于本地生成器存在路径遍历，可能导致任意文件读取。
