Overview
CVE-2025-66114 identifies a critical security vulnerability affecting the “Show Variations as Single Products Woocommerce” plugin, also known as woo-show-single-variations-shop-category, for WordPress WooCommerce. This vulnerability, classified as a Missing Authorization issue, allows for the potential exploitation of incorrectly configured access control security levels. Specifically, versions up to and including 2.0 are affected.
Technical Details
The vulnerability stems from a lack of proper authorization checks within the plugin’s code. This allows unauthorized users to potentially access or manipulate product variations that should be restricted to specific user roles or administrative access. While the specific exploitation vector requires further investigation of the plugin’s codebase, the core issue is a broken access control mechanism.
Essentially, the plugin fails to adequately verify if a user has the necessary permissions to view or interact with product variations, potentially leading to information disclosure or even modification of product data.
CVSS Analysis
Currently, the CVE entry for CVE-2025-66114 does not list a CVSS score or severity rating (N/A). However, the nature of a Missing Authorization vulnerability suggests a potentially high impact, depending on the extent of access that can be gained. Given the potential for unauthorized access to product data and configuration, we strongly recommend treating this vulnerability with high priority, regardless of the current N/A score. A proper CVSS score likely hasn’t been calculated yet, but given the nature of the vulnerability, a score in the medium to high range would be appropriate once calculated.
Possible Impact
The exploitation of CVE-2025-66114 could have several negative consequences for WooCommerce store owners:
- Information Disclosure: Unauthorized users could gain access to sensitive product variation data, such as pricing, stock levels, and other confidential details.
- Data Modification: In a worst-case scenario, attackers might be able to modify product variations, potentially altering pricing, descriptions, or even disabling products.
- Reputational Damage: Exploitation of this vulnerability could erode customer trust and damage the store’s reputation.
- Competitive Disadvantage: Competitors could potentially use the exposed information to gain an unfair advantage.
Mitigation and Patch Steps
The best course of action is to take the following steps:
- Update the Plugin: Immediately update the “Show Variations as Single Products Woocommerce” plugin to the latest available version. If a patch is available, apply it promptly. Keep monitoring the plugin developer’s website or the WordPress plugin repository for updates.
- Disable the Plugin (If No Update Available): If no update or patch is currently available, temporarily disable the plugin until a fix is released. This will prevent potential exploitation of the vulnerability.
- Review User Permissions: Carefully review user roles and permissions within your WooCommerce store to ensure that access is appropriately restricted.
- Monitor for Suspicious Activity: Keep a close eye on your store’s logs for any unusual or suspicious activity that could indicate exploitation attempts.
- Implement a Web Application Firewall (WAF): A WAF can provide an additional layer of security by filtering malicious traffic and preventing exploitation attempts.
