CVE-2026-24046 (CNNVD-202601-3330)
中文标题:
Backstage 后置链接漏洞
英文标题:
Backstage has a Possible Symlink Path Traversal in Scaffolder Actions
漏洞描述
中文描述:
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存在后置链接漏洞，该漏洞源于多个Scaffolder操作和存档提取工具容易受到基于符号链接的路径遍历攻击，可能导致读取、删除或写入任意文件。
英文描述:
Backstage is an open framework for building developer portals. Multiple Scaffolder actions and archive extraction utilities were vulnerable to symlink-based path traversal attacks. An attacker with access to create and execute Scaffolder templates could exploit symlinks to read arbitrary files via the `debug:log` action by creating a symlink pointing to sensitive files (e.g., `/etc/passwd`, configuration files, secrets); delete arbitrary files via the `fs:delete` action by creating symlinks pointing outside the workspace, and write files outside the workspace via archive extraction (tar/zip) containing malicious symlinks. This affects any Backstage deployment where users can create or execute Scaffolder templates. This vulnerability is fixed in `@backstage/backend-defaults` versions 0.12.2, 0.13.2, 0.14.1, and 0.15.0; `@backstage/plugin-scaffolder-backend` versions 2.2.2, 3.0.2, and 3.1.1; and `@backstage/plugin-scaffolder-node` versions 0.11.2 and 0.12.3. Users should upgrade to these versions or later. Some workarounds are available. Follow the recommendation in the Backstage Threat Model to limit access to creating and updating templates, restrict who can create and execute Scaffolder templates using the permissions framework, audit existing templates for symlink usage, and/or run Backstage in a containerized environment with limited filesystem access.
