CVE-2026-30240— Budibase 安全漏洞

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。
