## Vulnerability Details **CWE-918**: Server-Side Request Forgery (SSRF) The `processUrlFile` function in `packages/server/src/automations/steps/ai/extract.ts` uses `fetch(fileUrl)` directly **without the IP blacklist validation** that is consistently applied to all other automation steps. This allows an authenticated user to trigger server-side requests to internal network addresses. ### Vulnerable Code **`packages/server/src/automations/steps/ai/extract.ts` (lines 116, 139)**: ```typescript async function processUrlFile(fileUrl: string, ...): Promise { const response = await fetch(fileUrl) // NO blacklist check! // ... const fallbackResponse = await fetch(fileUrl) // Also NO blacklist check! } ``` ### Contrast with All Other Automation Steps (Same Codebase) Every other automation step that makes outbound HTTP requests properly uses `fetchWithBlacklist`: - `steps/slack.ts:19`: `response = await fetchWithBlacklist(url, {...})` - `steps/discord.ts:28`: `response = await fetchWithBlacklist(url, {...})` - `steps/zapier.ts:33`: `response = await fetchWithBlacklist(url, {...})` - `steps/n8n.ts:53`: `response = await fetchWithBlacklist(url, request)` - `step

What to do next
- investigate
Identify the exact component and deployed version, examine the linked publisher’s conditions, and retain evidence of any mitigation.
Confirm current vendor support, compatibility and deployment evidence. This report has not tested a fix in your system. GitHub Advisory Database
A fixed release is not deployment evidence.
Check current vendor support and compatibility. After making a change, verify the deployed build and relevant runtime conditions. Keep the evidence, owner and time. An updated lockfile alone does not prove what is running.
