CVE-2025-7897 is a vulnerability identified in the MoneyPrinterTurbo software developed by harry0703, affecting versions 1.2.0 through 1.2.6. The flaw resides in the verify_token function within the app/controllers/base.py file, which is part of the API endpoint component. The vulnerability results in missing authentication controls, allowing an attacker to bypass authentication mechanisms remotely without requiring any privileges or user interaction. This means that an attacker can potentially access or manipulate the API endpoints without proper verification, leading to unauthorized access. The CVSS 4.0 score of 6.9 classifies this as a medium severity issue, reflecting the ease of remote exploitation (no authentication or user interaction needed) but with limited impact on confidentiality, integrity, and availability (each rated low). The absence of authentication on critical API endpoints can allow attackers to perform unauthorized actions, potentially exposing sensitive data or enabling further attacks within the affected system. However, there are no known exploits in the wild at the time of publication, and no patches have been officially released yet. The vulnerability's exploitation scope is network-based, and it does not require any user interaction or privileges, increasing the risk of automated or widespread attacks once exploit code becomes available.

For European organizations using MoneyPrinterTurbo versions 1.2.0 to 1.2.6, this vulnerability poses a significant risk of unauthorized access to financial or transactional APIs, potentially leading to data leakage, fraudulent transactions, or disruption of financial operations. Given that MoneyPrinterTurbo is likely used in financial or accounting contexts, unauthorized API access could compromise sensitive financial data or enable manipulation of monetary records. This could result in regulatory compliance issues under GDPR due to exposure of personal or financial data, reputational damage, and financial losses. The remote and unauthenticated nature of the vulnerability increases the risk of exploitation by cybercriminals or state-sponsored actors targeting European financial institutions or businesses. The medium severity rating suggests that while the vulnerability is serious, the impact on confidentiality, integrity, and availability is somewhat limited, possibly due to compensating controls or the specific API functionality affected. Nonetheless, the potential for unauthorized access to financial APIs makes this a critical concern for organizations handling sensitive financial data or transactions within Europe.

European organizations should immediately assess their use of MoneyPrinterTurbo and identify any instances running affected versions (1.2.0 to 1.2.6). Until an official patch is released, organizations should implement compensating controls such as restricting network access to the API endpoints via firewalls or VPNs, enforcing strict IP whitelisting, and monitoring API traffic for anomalous or unauthorized requests. Application-level mitigations could include adding additional authentication or token validation layers externally to the vulnerable API endpoints. Organizations should also conduct thorough logging and real-time monitoring of API access to detect potential exploitation attempts. Regular vulnerability scanning and penetration testing focused on API security should be prioritized. Once a patch becomes available, organizations must apply it promptly. Additionally, reviewing and hardening the overall API security posture, including rate limiting, anomaly detection, and multi-factor authentication for administrative access, will reduce exploitation risk.
