CVE-2026-30240— Budibase PWA ZIP Upload Path Traversal Allows Reading Arbitrary Server Files Including All Environment Secrets

Budibase PWA ZIP Upload Path Traversal Allows Reading Arbitrary Server Files Including All Environment Secrets

Budibase is a low code platform for creating internal tools, workflows, and admin panels. In 3.31.5 and earlier, a path traversal vulnerability in the PWA (Progressive Web App) ZIP processing endpoint (POST /api/pwa/process-zip) allows an authenticated user with builder privileges to read arbitrary files from the server filesystem, including /proc/1/environ which contains all environment variables — JWT secrets, database credentials, encryption keys, and API tokens. The server reads attacker-specified files via unsanitized path.join() with user-controlled input from icons.json inside the uploaded ZIP, then uploads the file contents to the object store (MinIO/S3) where they can be retrieved through signed URLs. This results in complete platform compromise as all cryptographic secrets and service credentials are exfiltrated in a single request.

对路径名的限制不恰当(路径遍历)

Budibase 安全漏洞

Budibase是英国Budibase开源的一个用于在几分钟内创建内部应用程序、工作流和管理面板的低代码平台。 Budibase 3.31.5及之前版本存在安全漏洞，该漏洞源于PWA ZIP处理端点存在路径遍历问题，可能导致经过身份验证的用户读取服务器上的任意文件，进而导致平台完全被破解。
