CVE-2025-62151 is a missing authorization vulnerability identified in the Virtuaria PagBank / PagSeguro plugin for WooCommerce, affecting all versions up to and including 3.6.3. This vulnerability arises from incorrectly configured access control security levels, allowing attackers with low privileges (PR:L) to bypass authorization checks without requiring user interaction (UI:N). The vulnerability is remotely exploitable over the network (AV:N) and impacts the confidentiality, integrity, and availability of the affected systems (C:H/I:H/A:H). Specifically, an attacker could manipulate or access sensitive payment processing functions or data within the WooCommerce environment, potentially leading to unauthorized transactions, data leakage, or disruption of payment services. The plugin is widely used in e-commerce setups that integrate PagBank / PagSeguro payment solutions, which are popular in Latin America but also have adoption in European markets through WooCommerce stores. Although no public exploits have been reported yet, the high CVSS score of 8.8 underscores the critical nature of this vulnerability. The lack of patches at the time of publication necessitates immediate attention to access control configurations and monitoring. The vulnerability was reserved in early October 2025 and published in December 2025, indicating recent discovery and disclosure.

For European organizations, this vulnerability poses a significant threat to e-commerce platforms relying on the Virtuaria PagBank / PagSeguro WooCommerce plugin. Exploitation could lead to unauthorized access to payment processing functions, resulting in financial fraud, theft of customer payment data, and disruption of online sales operations. The compromise of confidentiality could expose sensitive customer information, violating GDPR and other data protection regulations, leading to legal and reputational consequences. Integrity impacts could allow attackers to alter transaction data or payment configurations, causing financial losses and undermining trust. Availability impacts could disrupt payment processing, leading to downtime and lost revenue. Given the critical role of payment gateways in online commerce, the vulnerability could also facilitate broader attacks on the hosting infrastructure or connected systems. European businesses with significant e-commerce presence, especially those using WooCommerce with this plugin, face elevated risks. The absence of known exploits currently provides a window for proactive mitigation, but the ease of exploitation and high impact necessitate urgent action.

1. Monitor Virtuaria's official channels for security patches and apply updates to the PagBank / PagSeguro WooCommerce plugin immediately upon release. 2. Until patches are available, implement strict access control measures at the web server and application levels to restrict access to sensitive payment processing endpoints only to trusted users and IP addresses. 3. Conduct a thorough review and hardening of WooCommerce user roles and permissions to minimize the number of users with privileges that could exploit this vulnerability. 4. Employ Web Application Firewalls (WAF) with custom rules to detect and block suspicious requests targeting the plugin's endpoints. 5. Enable detailed logging and real-time monitoring of payment-related transactions and administrative actions to detect anomalous activities promptly. 6. Educate e-commerce administrators about the vulnerability and the importance of limiting privileged access. 7. Consider temporary disabling or replacing the affected plugin with alternative payment solutions if immediate patching is not feasible. 8. Perform regular security assessments and penetration testing focused on access control mechanisms within the WooCommerce environment.
