CVE-2026-33003
Jenkins LoadNinja Plugin 2.
Executive Summary
CVE-2026-33003 is a medium severity vulnerability affecting pii-secrets. It is classified as Cleartext Storage. Ensure your systems and dependencies are patched immediately to mitigate exposure risks.
Precogs AI Insight
"This critical flaw stems from within Jenkins LoadNinja Plugin 2.1, allowing a failure to enforce strict data boundary conditions. In a real-world scenario, an attacker could exploit this by intercept or modify sensitive data flows before they reach secure enclaves. Precogs identifies and blocks the exfiltration of personally identifiable information to ensure strict authentication requirements are met."
What is this vulnerability?
CVE-2026-33003 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.
Jenkins LoadNinja Plugin 2.1 and earlier stores LoadNinja API keys unencrypted in job config.xml files on the Jenkins controller where they can be viewed b...
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]');

Vulnerability Code Signature
Attack Data Flow
| Stage | Detail |
|---|---|
| Source | User credentials or sensitive data |
| Vector | Data is stored without encryption or hashing |
| Sink | Database or file system |
| Impact | Data breach, unauthorized access |
Vulnerable Code Pattern
// ❌ VULNERABLE: Cleartext Storage
public void savePassword(String username, String password) {
// Taint sink: saving password in plain text
db.execute("INSERT INTO users (username, password) VALUES (?, ?)", username, password);
}
Secure Code Pattern
// ✅ SECURE: Secure Hashing
import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;
public void savePassword(String username, String password) {
BCryptPasswordEncoder encoder = new BCryptPasswordEncoder();
String hashedPassword = encoder.encode(password);
// Sanitized storage
db.execute("INSERT INTO users (username, password) VALUES (?, ?)", username, hashedPassword);
}
