CVE-2025-60159 is a security vulnerability classified under CWE-862 (Missing Authorization) affecting the webmaniabr Nota Fiscal Eletrônica WooCommerce plugin, specifically versions up to 3.4.0.6. This vulnerability arises due to improperly configured access control mechanisms within the plugin, which is designed to integrate Brazilian electronic invoicing (Nota Fiscal Eletrônica) functionality into WooCommerce, a popular e-commerce platform for WordPress. The missing authorization flaw means that certain actions or data access points within the plugin do not adequately verify whether the requesting user has the necessary permissions to perform those actions. As a result, an attacker with at least low-level privileges (PR:L) can exploit this weakness remotely (AV:N) without requiring user interaction (UI:N) to perform unauthorized operations that impact the integrity of the system or data. The CVSS v3.1 base score of 4.3 (medium severity) reflects that while the vulnerability does not affect confidentiality or availability, it can lead to integrity violations, such as unauthorized modification or manipulation of invoicing data or related configurations. The scope remains unchanged (S:U), indicating the vulnerability affects only the vulnerable component and does not propagate to other system components. No known exploits are currently reported in the wild, and no patches have been linked yet, suggesting that organizations using this plugin should proactively monitor for updates and consider temporary mitigations. Given the plugin’s role in handling critical invoicing data, exploitation could undermine the accuracy and trustworthiness of financial records, potentially causing compliance issues and financial discrepancies.

For European organizations, the direct impact of this vulnerability depends on the adoption of the webmaniabr Nota Fiscal Eletrônica WooCommerce plugin, which primarily targets Brazilian electronic invoicing requirements. However, European companies operating e-commerce platforms with cross-border sales or subsidiaries in Brazil might use this plugin or similar integrations. Exploitation could lead to unauthorized modification of invoicing data, risking financial integrity and regulatory compliance, especially under strict EU data protection and financial reporting regulations such as GDPR and the EU VAT Directive. Even if the plugin is not widely used in Europe, the vulnerability highlights risks in third-party e-commerce plugins that handle sensitive financial data. Attackers exploiting missing authorization flaws can manipulate transactional data, potentially facilitating fraud, tax evasion, or disrupting business operations. This could damage organizational reputation and lead to legal penalties. Furthermore, if attackers leverage this vulnerability as a foothold, they might escalate privileges or move laterally within the network, increasing the overall risk posture.

European organizations should first verify whether they use the webmaniabr Nota Fiscal Eletrônica WooCommerce plugin, particularly versions up to 3.4.0.6. If so, they should immediately restrict access to the plugin’s administrative and invoicing interfaces to trusted personnel only, implementing strict role-based access controls within WordPress and WooCommerce. Network-level restrictions such as IP whitelisting for administrative endpoints can reduce exposure. Monitoring and logging access to invoicing functions should be enhanced to detect anomalous or unauthorized activities promptly. Organizations should subscribe to vendor and security advisories to apply patches as soon as they become available. In the absence of patches, consider disabling or replacing the plugin with alternative solutions that enforce proper authorization checks. Additionally, conduct regular audits of invoicing data integrity and reconcile with external financial records to detect potential tampering. Implementing Web Application Firewalls (WAFs) with custom rules to block suspicious requests targeting the plugin’s endpoints can provide temporary protection. Finally, educate administrators and developers about the risks of missing authorization vulnerabilities and enforce secure coding and configuration practices for all third-party plugins.
