CVE-2025-7897: Authentication Bypass in MoneyPrinterTurbo
MoneyPrinterTurbo, a seemingly innocuous application (version 1.2.6 and earlier), has been found to harbor a critical vulnerability that could allow attackers to bypass authentication and potentially gain unauthorized access. Let's dive into the details and discuss how to protect yourself.
Vulnerability Details
- CVE ID: CVE-2025-7897
- Description: A critical authentication bypass vulnerability exists in the
verify_tokenfunction within theapp/controllers/base.pyfile of MoneyPrinterTurbo up to version 1.2.6. This flaw allows remote attackers to bypass authentication mechanisms. - CVSS Score: 7.3 (HIGH)
- CVSS Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L
- CVSS Explanation:
- AV:N (Network): The vulnerability is exploitable over the network.
- AC:L (Low): The attack requires little to no specialized access conditions.
- PR:N (None): No privileges are required to exploit the vulnerability.
- UI:N (None): No user interaction is required.
- S:U (Unchanged): The security scope is unchanged.
- C:L (Low): There is limited impact on data confidentiality.
- I:L (Low): There is limited impact on data integrity.
- A:L (Low): There is limited impact on system availability.
- Exploit Requirements: An attacker only needs network access to the affected system and knowledge of the vulnerable API endpoint.
- Affected Vendor: harry0703
- Affected Product: MoneyPrinterTurbo
- Affected Version: Up to 1.2.6
- CWE:
- CWE-287 (Improper Authentication): The application does not adequately verify the identity of the user or system attempting to access a resource.

Exploitability & Real-World Risk
Due to the lack of proper authentication, a remote attacker can potentially bypass security measures and access sensitive data or functionality. This could lead to data breaches, unauthorized actions, or disruption of service. Given the ease of exploitation (no special skills required), the real-world risk is significant.
Recommendations
The most critical recommendation is to update MoneyPrinterTurbo to a patched version as soon as it becomes available. If an update is not yet available, consider the following mitigation strategies:
- Disable the vulnerable API endpoint: If possible, temporarily disable the
verify_tokenfunction or the entire API endpoint until a patch is released. - Implement a Web Application Firewall (WAF): A WAF can help detect and block malicious requests targeting the vulnerable endpoint.
- Monitor network traffic: Closely monitor network traffic for suspicious activity targeting the MoneyPrinterTurbo application.
Technical Insight
The vulnerability likely stems from a flaw in how the verify_token function validates authentication tokens. It's possible that the function is not properly checking the validity or authenticity of the token, allowing attackers to forge or bypass the authentication process. A proper implementation of token verification is crucial for securing APIs.
