CVE-2026-27702— Budibase 安全漏洞

Budibase Vulnerable to Remote Code Execution via Unsafe eval() in View Filter Map Function (Budibase Cloud)

Budibase is a low code platform for creating internal tools, workflows, and admin panels. Prior to version 3.30.4, an unsafe `eval()` vulnerability in Budibase's view filtering implementation allows any authenticated user (including free tier accounts) to execute arbitrary JavaScript code on the server. This vulnerability ONLY affects Budibase Cloud (SaaS) - self-hosted deployments use native CouchDB views and are not vulnerable. The vulnerability exists in `packages/server/src/db/inMemoryView.ts` where user-controlled view map functions are directly evaluated without sanitization. The primary impact comes from what lives inside the pod's environment: the `app-service` pod runs with secrets baked into its environment variables, including `INTERNAL_API_KEY`, `JWT_SECRET`, CouchDB admin credentials, AWS keys, and more. Using the extracted CouchDB credentials, we verified direct database access, enumerated all tenant databases, and confirmed that user records (email addresses) are readable. Version 3.30.4 contains a patch.

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 3.30.4之前版本存在安全漏洞，该漏洞源于Budibase视图过滤实现中存在不安全的eval()漏洞，允许任何经过身份验证的用户在服务器上执行任意JavaScript代码，可能导致环境变量中的密钥和凭据泄露。
