CVE-2025-66114 is a vulnerability identified in the 'Show Variations as Single Products Woocommerce' plugin developed by theme funda. This plugin allows WooCommerce stores to display product variations as individual products. The vulnerability arises from missing authorization checks, meaning that certain actions or data exposures that should be restricted to authorized users are accessible without any authentication or user interaction. Specifically, the plugin incorrectly configures access control security levels, enabling remote attackers to exploit this flaw over the network without requiring privileges or user interaction. The affected versions include all releases up to and including version 2.0. The vulnerability primarily impacts confidentiality by potentially exposing sensitive product variation data or related information that should be restricted. The CVSS 3.1 base score is 5.3 (medium severity), with vector AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N, indicating network attack vector, low attack complexity, no privileges required, no user interaction, unchanged scope, limited confidentiality impact, and no impact on integrity or availability. No known exploits have been reported in the wild as of the publication date. The lack of patches currently available means organizations must rely on compensating controls until vendor fixes are released. This vulnerability is particularly relevant to WooCommerce-based e-commerce websites that utilize this plugin to enhance product variation display and sales. Attackers exploiting this flaw could gain unauthorized access to product variation data, potentially leading to information disclosure that could be leveraged for further attacks or competitive intelligence gathering.

For European organizations operating WooCommerce e-commerce platforms with the affected plugin, this vulnerability could lead to unauthorized disclosure of product variation data, which may include pricing, stock levels, or other sensitive commercial information. While the impact does not extend to data integrity or availability, the confidentiality breach could undermine competitive advantage and customer trust. Retailers and businesses relying on WooCommerce for online sales could face reputational damage if sensitive data is exposed. Additionally, attackers might use the disclosed information to craft more targeted phishing or fraud campaigns. Given the medium severity and ease of exploitation (no authentication or user interaction required), the risk is non-trivial, especially for high-volume e-commerce sites. The absence of known exploits in the wild reduces immediate risk but does not eliminate the threat, as public disclosure may prompt attackers to develop exploits. European organizations must consider the potential impact on compliance with data protection regulations such as GDPR, particularly if customer-related data is indirectly exposed through this vulnerability.

1. Monitor the vendor's official channels for patches or updates addressing CVE-2025-66114 and apply them promptly once available. 2. Until patches are released, restrict access to the affected plugin's functionalities by implementing web application firewall (WAF) rules that limit access to trusted IP ranges or require additional authentication layers. 3. Conduct thorough access control reviews and harden WooCommerce configurations to minimize exposure of sensitive endpoints. 4. Employ security monitoring and anomaly detection to identify unusual access patterns or data requests related to product variations. 5. Consider temporarily disabling or replacing the plugin with alternative solutions that do not exhibit this vulnerability if the risk is deemed unacceptable. 6. Educate development and operations teams about the risks of missing authorization vulnerabilities and enforce secure coding and configuration practices for third-party plugins. 7. Regularly audit all WooCommerce plugins for security updates and vulnerabilities to maintain a secure e-commerce environment.
