NocoBase is an AI-powered no-code/low-code platform for building business applications and enterprise solutions. Prior to version 2.0.37, NocoBase's workflow HTTP request plugin and custom request action plugin make server-side HTTP requests to user-provided URLs without any SSRF protection. An authenticated user can access internal network services, cloud metadata endpoints, and localhost. Version 2.0.37 contains a patch.

GHSA-mvvv-v22x-xqwp — NocoBase has SSRF in Workflow HTTP Request and Custom Request Plugins

Affected: npm: @nocobase/plugin-workflow-request

## Summary

NocoBase's workflow HTTP request plugin and custom request action plugin make server-side HTTP requests to user-provided URLs without any SSRF protection. An authenticated user can access internal network services, cloud metadata endpoints, and localhost.

## Vulnerable Code

### 1. Workflow HTTP Request Plugin

**`packages/plugins/@nocobase/plugin-workflow-request/src/server/RequestInstruction.ts` lines 117-128:** ```typescript return axios.request({ url: trim(url), // User-controlled, no validation method, headers, params, timeout, ...(method.toLowerCase() !== 'get' && data != null ? { data: transformer ? await transformer(data) : data } : {}), }); ```

The `url` at line 98 comes directly from user workflow configuration with only whitespace trimming.

### 2. Custom Request Action Plugin

**`packages/plugins/@nocobase/plugin-action-custom-request/src/server/actions/send.ts` lines 172-198:** ```typescript const axiosRequestConfig = { baseURL: ctx.origin, ...options, url: getParsedValue(url, variables), // User-controlled via template headers: { ... }, params: getParsedValue(arrayToObject(params), variables), data: getParsedValue(toJSON(data), variables), }; const res = await axios(axiosRequestConfig); // No IP validation ```

## Missing Protections

- No `request-filtering-agent` or SSRF library (confirmed via grep across entire codebase) - No private IP range filtering - No cloud metadata endpoint blocking - No URL scheme vali…
