CVE-2025-68157
webpack buildHttp HttpUriPlugin allowedUris bypass via HTTP redirects → SSRF + cache persistence
Executive Summary
CVE-2025-68157 is a high severity vulnerability affecting pii-secrets. It is classified as an undisclosed flaw. Ensure your systems and dependencies are patched immediately to mitigate exposure risks.
Precogs AI Insight
"The underlying mechanism of this vulnerability involves within ### Summary, allowing flawed state management logic. A threat actor could leverage this oversight to seize control of the underlying infrastructure and pivot to adjacent networks. The Precogs PII & Secrets Scanner mitigates this by flagging exposed sensitive data patterns to flag these architectural defects instantly."
What is this vulnerability?
CVE-2025-68157 is categorized as a critical Code Injection / RCE flaw. Based on our vulnerability intelligence, this issue occurs when the application fails to securely handle untrusted data boundaries.
Summary When experiments.buildHttp is enabled, webpack’s HTTP(S) resolver (HttpUriPlugin) enforces allowedUris only for the initial URL, but .
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.

Impact on Systems
✅ Remote Code Execution: Attackers achieve arbitrary command execution within the context of the application server.
✅ Privilege Escalation: Initial code execution can be exploited to pivot and elevate privileges across the network.
✅ Persistent Backdoors: Attackers can bind reverse shells, modify source files, or inject persistent access mechanisms.
How to fix this issue?
Implement the following strategic mitigations immediately to eliminate the attack surface.
1. Remove Dynamic Evaluation Completely eliminate the use of dynamic evaluation functions (eval(), exec(), system()) on untrusted input.
2. Sandboxing If dynamic execution is an absolute business requirement, isolate the execution environment in tightly constrained, non-networked sandboxes (e.g., restricted WebAssembly or isolated containers).
3. Network Segmentation Restrict outbound traffic from the application server (egress filtering) to prevent reverse shell connections.
Vulnerability Signature
// Vulnerable Node.js Execution
const exec = require('child_process').exec;
const user_domain = req.query.domain;
// VULNERABLE: Injecting user input directly into system shell commands
exec('ping -c 4 ' + user_domain, (error, stdout, stderr) =\> \{
res.send(stdout);
\});
// EXPLOIT PAYLOAD: precogs.ai ; cat /etc/passwd

Attack Data Flow
| Stage | Detail |
|---|---|
| Source | Source code repository or API response |
| Vector | Secrets embedded directly in the codebase or PII leaked in response |
| Sink | Version control system or HTTP response |
| Impact | Data breach, unauthorized access, compliance violation |
Vulnerable Code Pattern
// ❌ VULNERABLE: Hardcoded credential & PII Leak
public class Config {
// Taint sink: secret embedded in code
public static final String API_KEY = "sk_live_1234567890abcdef";
}
// ... API Response leaks full user details including SSN ...
Secure Code Pattern
// ✅ SECURE: Environment variables & Data Masking
public class Config {
// Sanitized configuration
public static final String API_KEY = System.getenv("STRIPE_API_KEY");
}
// ... API Response masks SSN and restricts PII exposure ...
