  "summary" : "NocoBase has SSRF in Workflow HTTP Request and Custom Request Plugins",
  "details" : "## Summary\n\nNocoBase'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.\n\n## Vulnerable Code\n\n### 1. Workflow HTTP Request Plugin\n\n**`packages/plugins/@nocobase/plugin-workflow-request/src/server/RequestInstruction.ts` lines 117-128:**\n```typescript\nreturn axios.request({\n  url: trim(url),  // User-controlled, no validation\n  method,\n  headers,\n  params,\n  timeout,\n  ...(method.toLowerCase() !== 'get' && data != null\n    ? { data: transformer ? await transformer(data) : data }\n    : {}),\n});\n```\n\nThe `url` at line 98 comes directly from user workflow configuration with only whitespace trimming.\n\n### 2. Custom Request Action Plugin\n\n**`packages/plugins/@nocobase/plugin-action-custom-request/src/server/actions/send.ts` lines 172-198:**\n```typescript\nconst axiosRequestConfig = {\n  baseURL: ctx.origin,\n  ...options,\n  url: getParsedValue(url, variables),  // User-controlled via template\n  headers: { ... },\n  params: getParsedValue(arrayToObject(params), variables),\n  data: getParsedValue(toJSON(data), variables),\n};\nconst res = await axios(axiosRequestConfig);  // No IP validation\n```\n\n## Missing Protections\n\n- No `request-filtering-agent` or SSRF library (confirmed via grep across entire codebase)\n- No private IP range filtering\n- No cloud metadata endpoint blocking\n- No URL scheme validation\n- No DNS rebinding protection\n\n## Attack Scenario\n\n1. Authenticated user creates a workflow with HTTP Request node\n2. Sets URL to `http://169.254.169.254/latest/meta-data/iam/security-credentials/`\n3. Triggers the workflow\n4. Server fetches AWS metadata and returns IAM credentials in workflow execution logs\n\nAlternatively via Custom Request action:\n1. Create custom request with URL `http://127.0.0.1:5432` or `http://10.0.0.1:8080/admin`\n2. Execute the action\n3. Server makes request to internal service\n\n## Impact\n\n- **Cloud metadata theft**: AWS/GCP/Azure credentials via metadata endpoints\n- **Internal network access**: Scan and interact with services on private IP ranges\n- **Database access**: Connect to localhost databases (PostgreSQL, Redis, etc.)\n- **Authentication required**: Yes (authenticated user), but any workspace member can create workflows",
