CVE-2025-48446 is a high-severity vulnerability classified under CWE-863 (Incorrect Authorization) affecting the Drupal Commerce Alphabank Redirect module versions prior to 1.0.3, specifically version 0.0.0 as indicated. This vulnerability arises due to improper authorization checks within the module's redirect functionality, which is designed to handle payment redirections to Alphabank, a financial institution. The flaw allows an attacker to misuse the functionality by bypassing intended access controls, potentially enabling unauthorized users to perform actions or access resources that should be restricted. The CVSS 3.1 base score of 8.8 reflects the critical nature of this vulnerability, with an attack vector of network (AV:N), low attack complexity (AC:L), no privileges required (PR:N), but requiring user interaction (UI:R). The impact metrics indicate high confidentiality (C:H), integrity (I:H), and availability (A:H) impacts, meaning exploitation could lead to full compromise of sensitive data, unauthorized modification of information, and disruption of service. Although no known exploits are currently reported in the wild, the vulnerability's characteristics suggest it could be leveraged for significant attacks, such as redirecting payment flows, stealing sensitive transaction data, or manipulating commerce processes. The lack of available patches at the time of publication increases the urgency for organizations to implement interim mitigations. Given Drupal's widespread use in e-commerce and content management, especially in Europe, this vulnerability poses a substantial risk to organizations relying on the Commerce Alphabank Redirect module for payment processing.

For European organizations, the impact of CVE-2025-48446 is considerable due to the critical role of e-commerce platforms in the regional economy and the stringent regulatory environment surrounding payment data (e.g., GDPR, PSD2). Exploitation could lead to unauthorized access to payment redirection mechanisms, enabling attackers to intercept or alter payment flows, potentially resulting in financial fraud, data breaches involving personal and payment information, and reputational damage. The high confidentiality impact threatens customer data privacy, while integrity and availability impacts could disrupt business operations and erode trust in online commerce platforms. Additionally, compromised payment redirection could facilitate money laundering or other illicit financial activities, attracting regulatory scrutiny and legal consequences. Organizations in sectors such as retail, finance, and services that utilize Drupal Commerce with the Alphabank Redirect module are particularly vulnerable. The requirement for user interaction implies phishing or social engineering could be vectors, increasing the risk profile in environments with less user awareness or training.

Given the absence of an official patch at the time of this analysis, European organizations should implement the following specific mitigations: 1) Immediately audit and restrict access to the Commerce Alphabank Redirect module configuration and usage to trusted administrators only, minimizing exposure. 2) Implement strict web application firewall (WAF) rules to monitor and block suspicious redirect requests or anomalous traffic patterns targeting the payment redirection endpoints. 3) Conduct thorough code reviews and, if feasible, apply temporary custom authorization checks to enforce proper access controls around the redirect functionality. 4) Enhance user awareness training to recognize and avoid phishing attempts that could trigger the required user interaction for exploitation. 5) Monitor logs for unusual redirect activities or failed authorization attempts to detect early signs of exploitation. 6) Plan and prioritize upgrading to Commerce Alphabank Redirect version 1.0.3 or later as soon as it becomes available, ensuring the vulnerability is fully remediated. 7) Coordinate with payment processors and financial partners to establish additional transaction monitoring and fraud detection during the mitigation period.
