CVE-2025-46565
Vite's server.fs.deny bypassed with /. for files under project root
Executive Summary
CVE-2025-46565 is a critical 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 insufficient sanitization protocols during data parsing. In a real-world scenario, an attacker could exploit this by escalate their own privileges to administrative levels without proper credentials. Precogs identifies and blocks the exfiltration of personally identifiable information to intercept unsafe execution patterns."
What is this vulnerability?
CVE-2025-46565 is categorized as a critical Sensitive Data Exposure flaw. Based on our vulnerability intelligence, this issue occurs when the application fails to securely handle untrusted data boundaries.
Summary The contents of files in the project root that are denied by a file matching pattern can .
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
✅ Authentication Bypass: Leaked credentials allow attackers to impersonate legitimate users or systems.
✅ Data Breach: Exposed PII triggers regulatory violations (GDPR/CCPA) and massive reputational damage.
✅ Lateral Movement: Exposed API tokens can be used to pivot deeper into internal infrastructure.
How to fix this issue?
Implement the following strategic mitigations immediately to eliminate the attack surface.
1. Secret Management Migrate all hardcoded secrets to a secure vault (e.g., AWS Secrets Manager, HashiCorp Vault).
2. Data Masking Implement automated redaction for logs to prevent PII/credentials from leaking into observability platforms.
3. Automated Scanning Deploy Precogs Secrets Scanner in pre-commit hooks and CI pipelines to prevent secret commits.
Vulnerability Signature
// Generic Secrets Exposure Vector
// DANGEROUS: Hardcoded secrets in source control or logs
const apiKey = "sk_live_1234567890abcdef";
console.log(`Connecting to API with key $\{apiKey\}`);
// SECURED: Secrets fetched from environment at runtime
const apiKey = process.env.API_SECRET_KEY;
if (!apiKey) throw new Error("API configuration missing");
// Never log secrets
console.log('Connecting to API... [REDACTED]');

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 ...
