[AutoGPT] SSRF due to DNS Rebinding in requests wrapper
Executive Summary
CVE-2025-31490 is a high severity vulnerability affecting appsec, ai-code, binary-analysis, pii-secrets. It is classified as Server-Side Request Forgery. Ensure your systems and dependencies are patched immediately to mitigate exposure risks.
Precogs AI Insight
"The defect is inherently caused by within Description ===========, allowing a lack of rigorous type checking mechanisms. This flaw provides a direct pathway for attackers to seize control of the underlying infrastructure and pivot to adjacent networks. By intercepting insecure data flows from user input directly to rendering sinks, Precogs is designed to flag these architectural defects instantly."
What is this vulnerability?
CVE-2025-31490 is categorized as a critical Application Verification Flaw flaw. Based on our vulnerability intelligence, this issue occurs when the application fails to securely handle untrusted data boundaries.
Description ===========
AutoGPT uses a wrapper around the requests python library, located in [autogpt_platform/backend/backend/util/request.py](http.
This architectural defect enables adversaries to bypass intended security controls, directly manipulating the application's execution state or data layer. Immediate strategic intervention is required.
Risk Assessment
| Metric | Value |
|---|---|
| CVSS Base Score | 8 (HIGH) |
| Vector String | N/A |
| Published | April 11, 2025 |
| Last Modified | April 11, 2025 |
| Related CWEs | CWE-918 |
Impact on Systems
✅ Unauthorized Access: Flaws in application logic can permit unauthorized interaction with protected APIs.
✅ Data Manipulation: Adversaries may alter critical application states, such as user roles or configurations.
✅ Service Disruption: Improper error handling or unvalidated inputs can lead to resource exhaustion.
How to fix this issue?
Implement the following strategic mitigations immediately to eliminate the attack surface.
1. Defense in Depth Implement multi-layered validation (client-side, API gateway, and server-side).
2. Least Privilege Ensure backend service accounts operate with the absolute minimum rights required.
3. Security Regression Testing Integrate automated semantic security scanning into the deployment pipeline.
Vulnerability Signature
// Generic Application Security Flaw (Node.js)
app.post('/api/update-profile', (req, res) =\> \{
// DANGEROUS: Mass Assignment / Object Injection
// Attacker can pass \{ "isAdmin": true, "email": "..." \}
User.update(\{ id: req.user.id \}, req.body);
// SECURED: Explicitly select permitted fields
const \{ email, displayName, bio \} = req.body;
User.update(\{ id: req.user.id \}, \{ email, displayName, bio \});
\});

Vulnerability Code Signature
Attack Data Flow
| Stage | Detail |
|---|---|
| Source | User-supplied URL parameter |
| Vector | Server fetches the user-controlled URL |
| Sink | HTTP request library (e.g., fetch, axios) |
| Impact | Access to internal services, metadata endpoints, or port scanning |
Vulnerable Code Pattern
// ❌ VULNERABLE: Server-Side Request Forgery
app.get('/proxy', async (req, res) => {
const targetUrl = req.query.url;
// Taint sink: unvalidated outbound request
const response = await fetch(targetUrl);
res.send(await response.text());
});
Secure Code Pattern
// ✅ SECURE: Allowlist validation
const ALLOWED_DOMAINS = ['api.partner.com'];
app.get('/proxy', async (req, res) => {
const targetUrl = new URL(req.query.url);
if (!ALLOWED_DOMAINS.includes(targetUrl.hostname)) {
return res.status(403).send("Domain not allowed");
}
// Sanitized outbound request
const response = await fetch(targetUrl.href);
res.send(await response.text());
});
