CVE-2025-31580 identifies a missing authorization vulnerability in the Ni WooCommerce Product Enquiry plugin, versions up to and including 4.1.8, developed by Anzar Ahmed. The vulnerability arises because certain functionality within the plugin is not properly constrained by Access Control Lists (ACLs), allowing unauthorized users to invoke functions that should be restricted. This type of flaw typically results from inadequate validation of user permissions before executing sensitive operations. Since WooCommerce is a widely used e-commerce platform on WordPress, plugins like Ni WooCommerce Product Enquiry extend its capabilities by enabling customers to inquire about products. However, if authorization checks are missing or improperly implemented, attackers can potentially access or manipulate product enquiry data or related functionality without proper credentials. The vulnerability does not require authentication or user interaction, which increases its risk profile. No CVSS score has been assigned yet, and no known exploits have been reported in the wild, but the flaw's nature suggests it could be exploited to compromise confidentiality or integrity of e-commerce data. The vulnerability affects all versions up to 4.1.8, and no official patches or updates have been linked yet, indicating that users must monitor vendor communications for fixes or apply manual mitigations.

The missing authorization vulnerability could allow attackers to bypass security controls and access or manipulate product enquiry functionalities without proper permissions. This can lead to unauthorized disclosure of customer inquiries or product information, potentially exposing sensitive business or customer data. Attackers might also exploit this to perform unauthorized actions that could disrupt normal e-commerce operations, impacting data integrity and availability. For organizations, this could result in reputational damage, loss of customer trust, regulatory compliance issues, and financial losses due to fraud or operational disruption. Since WooCommerce powers a significant portion of online stores globally, the scope of affected systems is broad, increasing the potential impact. The ease of exploitation without authentication further elevates the threat level, making it attractive for opportunistic attackers. Although no active exploits are currently known, the vulnerability's presence in a popular plugin suggests a high risk if left unaddressed.

Organizations should immediately audit their WooCommerce installations to identify if the Ni WooCommerce Product Enquiry plugin is in use, particularly versions up to 4.1.8. Until an official patch is released, consider disabling the plugin or restricting access to its functionality via web application firewalls (WAF) or custom access controls. Implement strict role-based access controls (RBAC) at the WordPress and server levels to limit exposure. Monitor logs for unusual access patterns related to product enquiry endpoints. Engage with the plugin vendor or community to track patch releases and apply updates promptly once available. Additionally, conduct penetration testing focused on authorization checks within WooCommerce plugins to identify similar issues proactively. Educate development and security teams on secure coding practices to prevent missing authorization flaws in custom plugins or extensions.
