CVE-2025-51586 is a security vulnerability identified in PrestaShop, specifically within the file controllers/admin/AdminLoginController.php, affecting versions prior to 8.2.1. The vulnerability arises from the implementation of the password reset feature, which improperly handles sensitive information, allowing attackers to gain unauthorized access to such data. Although specific technical details such as the exact nature of the information leakage or the exploitation method are not provided, the vulnerability likely involves insufficient validation or exposure of sensitive tokens or user data during the password reset process. This could enable attackers to enumerate user accounts, retrieve password reset tokens, or otherwise compromise administrative credentials. The absence of a CVSS score and known exploits in the wild suggests that the vulnerability is newly disclosed and may not yet be widely exploited. However, given that it affects the admin login controller, the potential for privilege escalation or unauthorized administrative access is significant. PrestaShop is a widely used open-source e-commerce platform, and vulnerabilities in its administrative interfaces can have serious consequences for the confidentiality and integrity of merchant data and operations.

For European organizations using PrestaShop for their e-commerce operations, this vulnerability poses a considerable risk. Exploitation could lead to unauthorized access to administrative accounts, enabling attackers to manipulate store configurations, access customer data, or disrupt business operations. This could result in data breaches involving personal customer information, financial data, and order histories, potentially violating GDPR requirements and leading to regulatory penalties. Additionally, compromised administrative access could facilitate further attacks such as malware injection, fraudulent transactions, or denial of service. The impact extends beyond individual merchants to their customers and partners, potentially damaging reputation and trust. Given the widespread adoption of PrestaShop in Europe, especially among small and medium-sized enterprises (SMEs), the vulnerability could affect a broad range of organizations, from niche retailers to larger online stores.

Organizations should promptly update PrestaShop installations to version 8.2.1 or later, where this vulnerability is addressed. If immediate patching is not feasible, administrators should consider temporarily disabling the password reset feature or implementing additional verification steps such as multi-factor authentication (MFA) for administrative logins. Monitoring logs for unusual password reset requests or failed login attempts can help detect exploitation attempts. It is also advisable to review and tighten access controls around the admin interface, restricting access by IP address or VPN where possible. Regular security audits and penetration testing focused on authentication mechanisms can identify residual weaknesses. Finally, educating staff about phishing and social engineering risks related to password resets can reduce the likelihood of successful exploitation.
