CVE-2025-7897 Overview
A critical authentication bypass vulnerability has been identified in harry0703 MoneyPrinterTurbo up to version 1.2.6. The vulnerability exists in the verify_token function within the app/controllers/base.py file of the API Endpoint component. Due to missing authentication controls, remote attackers can access protected API endpoints without proper authorization, potentially gaining unauthorized access to application functionality and data.
Critical Impact
Remote attackers can bypass authentication mechanisms and access protected API endpoints without valid credentials, potentially leading to unauthorized data access, modification, or system compromise.

Technical Details for CVE-2025-7897
Vulnerability Analysis
This vulnerability is classified under CWE-287 (Improper Authentication) and CWE-306 (Missing Authentication for Critical Function). The issue stems from inadequate authentication enforcement in the API endpoint component of MoneyPrinterTurbo. The verify_token function in app/controllers/base.py fails to properly validate authentication tokens before granting access to protected resources, allowing unauthenticated users to interact with API endpoints that should require valid credentials.
The network-based attack vector means that any attacker with network access to the vulnerable application can exploit this flaw without requiring any prior authentication or user interaction.
Root Cause
The root cause of this vulnerability lies in the improper implementation of the verify_token function within the app/controllers/base.py file. The authentication mechanism either lacks proper token validation logic or contains conditional bypasses that allow requests to proceed without verifying the authenticity of the provided credentials. This represents a fundamental security design flaw where critical functions are exposed without adequate access controls.
Attack Vector
The attack is network-based and can be launched remotely against any exposed MoneyPrinterTurbo instance. An attacker can craft HTTP requests to API endpoints that would normally require authentication. Due to the missing authentication checks in the verify_token function, these requests are processed as if they came from an authenticated user.
The vulnerability does not require any user interaction or prior privileges to exploit. An attacker simply needs network access to the application's API endpoints to bypass authentication controls and access protected functionality.
Detection Methods for CVE-2025-7897
Indicators of Compromise
- Unusual API access patterns from unrecognized IP addresses without corresponding authentication events
- Missing or invalid authentication tokens in access logs that still result in successful API responses
- Abnormal data access or modification activity without legitimate user sessions
- Increased API traffic volumes from sources that have not completed authentication workflows
Detection Strategies
- Monitor API access logs for requests to protected endpoints that lack valid authentication headers
- Implement anomaly detection for API calls that bypass the normal authentication flow
- Review web server and application logs for requests to app/controllers/base.py endpoints without proper session tokens
- Deploy web application firewall (WAF) rules to detect and alert on unauthenticated access attempts
Monitoring Recommendations
- Enable verbose logging for all API authentication events and failures
- Configure alerts for authentication bypass attempts and unusual access patterns
- Monitor for rapid enumeration of API endpoints from single source IPs
- Track and baseline normal authenticated user behavior to identify anomalous unauthenticated access
How to Mitigate CVE-2025-7897
Immediate Actions Required
- Upgrade MoneyPrinterTurbo to a version newer than 1.2.6 that contains the authentication fix
- Implement network-level access controls to restrict API endpoint access to trusted sources only
- Review application logs for any signs of exploitation or unauthorized access
- Consider temporarily disabling public access to the application until patching is complete
Patch Information
Users should update MoneyPrinterTurbo to a version beyond 1.2.6 that addresses this authentication bypass vulnerability. For more information, consult the VulDB vulnerability entry which tracks this issue.
Workarounds
- Deploy a reverse proxy or web application firewall (WAF) to enforce authentication at the network perimeter
- Implement IP-based access control lists (ACLs) to limit API access to known trusted addresses
- Add external authentication middleware to validate requests before they reach the application
- Monitor and rate-limit API endpoints to reduce the impact of potential exploitation attempts
# Example: Restrict API access using iptables (adjust IP ranges as needed)
# Allow only trusted IP ranges to access the application port
iptables -A INPUT -p tcp --dport 8080 -s 10.0.0.0/8 -j ACCEPT
iptables -A INPUT -p tcp --dport 8080 -j DROP
