CVE-2025-54428: RevelaCode Information Disclosure Flaw

CVE-2025-54428 Overview

CVE-2025-54428 is a critical hardcoded credentials vulnerability affecting RevelaCode, an AI-powered faith-tech project that decodes biblical verses, prophecies, and global events. A valid MongoDB Atlas URI containing embedded username and password was accidentally committed to the public repository, exposing production or staging database credentials to unauthorized access.

This vulnerability falls under CWE-522 (Insufficiently Protected Credentials) and represents a severe security lapse that could allow attackers to exfiltrate, modify, or delete sensitive data from the exposed MongoDB database. The credentials were publicly accessible in the repository's .env file, making exploitation trivial for anyone with repository access.

Critical Impact

Complete database compromise possible through exposed MongoDB Atlas credentials, enabling unauthorized data exfiltration, modification, or deletion of production/staging databases.

Affected Products

• RevelaCode-Backend versions below 1.0.1

Technical Details for CVE-2025-54428

Vulnerability Analysis

This vulnerability represents a classic case of hardcoded credential exposure in version control. The RevelaCode-Backend project inadvertently committed a .env file containing a complete MongoDB Atlas connection URI with embedded authentication credentials. This type of secret exposure is particularly dangerous because Git repositories maintain complete history, meaning the credentials remain accessible even after removal from the current codebase unless the repository history is properly cleaned.

The exposed connection string contained a fully qualified MongoDB Atlas URI including the username, password, cluster address, and database name. This provides attackers with everything needed to establish a direct connection to the database from any network location, bypassing application-level security controls entirely.

Root Cause

The root cause is the accidental inclusion of sensitive credentials directly in source code files that were subsequently committed to a public repository. This violates secure development practices which mandate that secrets should never be stored in version-controlled files. Instead, secrets should be managed through environment variables loaded from external secret management systems or secure vault services.

The .env file, which should typically be listed in .gitignore, was either not properly excluded or was force-committed to the repository, exposing the MongoDB Atlas connection string with embedded credentials.

Attack Vector

The attack vector for this vulnerability is network-based and requires no privileges, authentication, or user interaction. An attacker simply needs to:

1. Access the public GitHub repository
2. Locate the exposed .env file or search the commit history
3. Extract the MongoDB Atlas connection URI
4. Connect directly to the database using any MongoDB client

The following shows the exposed credential pattern found in the commit:

 PORT=5000

Detection Methods for CVE-2025-54428

Indicators of Compromise

• Unexpected database connections from unrecognized IP addresses in MongoDB Atlas logs
• Unusual query patterns or bulk data export operations against the revelacode database
• Failed authentication attempts followed by successful logins from suspicious geographic locations
• Database modifications or deletions that do not correlate with legitimate application activity

Detection Strategies

• Implement MongoDB Atlas audit logging to track all database authentication and query events
• Monitor for connections originating from IP addresses outside expected application infrastructure
• Use GitHub secret scanning or tools like git-secrets to detect credential patterns in repository history
• Deploy network monitoring to identify outbound connections to MongoDB Atlas clusters from unauthorized systems

Monitoring Recommendations

• Enable MongoDB Atlas performance alerts and access logging features
• Configure alerting for new database user creation or permission changes
• Monitor repository commit history for any additional secret exposures using automated scanning tools
• Review MongoDB Atlas connection logs regularly for anomalous access patterns

How to Mitigate CVE-2025-54428

Immediate Actions Required

• Immediately rotate credentials for the exposed MongoDB database user
• Audit recent MongoDB Atlas access logs for any suspicious or unauthorized activity
• Upgrade to RevelaCode-Backend version 1.0.1 or later which removes the exposed credentials
• Review repository commit history and consider using BFG Repo-Cleaner or git filter-branch to purge sensitive data

Patch Information

The vulnerability has been addressed in RevelaCode-Backend version 1.0.1. The security fix is documented in GitHub Security Advisory GHSA-m253-qvcr-cr48 and the remediation commit is available at GitHub Commit 95005cf.

Organizations using affected versions should update immediately and rotate all potentially exposed database credentials.

Workarounds

• Use a secret manager such as HashiCorp Vault, Doppler, or AWS Secrets Manager instead of storing secrets directly in code
• Ensure .env files and other secret-containing files are properly listed in .gitignore before repository initialization
• Implement pre-commit hooks using tools like git-secrets or detect-secrets to prevent accidental credential commits
• Restrict MongoDB Atlas database user permissions to the minimum required for application functionality

# Example .gitignore configuration to prevent secret exposure
echo ".env" >> .gitignore
echo ".env.local" >> .gitignore
echo ".env.*.local" >> .gitignore
echo "*.pem" >> .gitignore
echo "secrets/" >> .gitignore

# Verify secrets are not tracked
git status --ignored
