CVE-2025-60211 is an Incorrect Privilege Assignment vulnerability found in the extendons WooCommerce Registration Fields Plugin - Custom Signup Fields, affecting versions up to 3.2.3. This plugin extends WooCommerce by allowing custom signup fields during user registration, commonly used in e-commerce websites built on WordPress. The vulnerability arises from improper handling of user privileges, enabling an authenticated user with limited rights to escalate their privileges without requiring any user interaction. The CVSS v3.1 score of 8.8 reflects a high-severity issue with network attack vector (AV:N), low attack complexity (AC:L), requiring privileges (PR:L), no user interaction (UI:N), and impacting confidentiality, integrity, and availability (C:H/I:H/A:H). Exploiting this flaw could allow attackers to gain administrative control over the WooCommerce site, manipulate user data, or disrupt services. While no public exploits are currently known, the vulnerability's nature and ease of exploitation make it a significant risk. The plugin's widespread use in European e-commerce platforms increases the potential impact, especially where sensitive customer data and payment information are processed. The vulnerability was reserved on 2025-09-25 and published on 2025-10-22, with no patch links currently available, indicating that organizations must monitor vendor updates closely.

For European organizations, this vulnerability poses a substantial risk to e-commerce platforms relying on WooCommerce with the affected plugin. Successful exploitation can lead to unauthorized privilege escalation, allowing attackers to access sensitive customer data, manipulate orders, or disrupt online sales operations. This can result in financial losses, reputational damage, and regulatory penalties under GDPR due to data breaches. The high severity and network exploitability mean attackers can remotely target vulnerable systems without user interaction, increasing the threat surface. Given the importance of e-commerce in countries like Germany, the UK, France, and the Netherlands, organizations in these regions could face significant operational and compliance challenges if exploited. Additionally, the integrity and availability impacts could disrupt business continuity, affecting customer trust and revenue streams.

European organizations should immediately audit their WooCommerce installations to identify the presence of the extendons Registration Fields Plugin - Custom Signup Fields and verify the version in use. Until an official patch is released, restrict access to the plugin's administrative functions by limiting user roles and permissions to the minimum necessary. Implement strict monitoring and alerting for unusual privilege escalations or administrative actions within the WordPress environment. Employ web application firewalls (WAF) with custom rules to detect and block suspicious requests targeting the plugin's endpoints. Regularly back up site data and configurations to enable rapid recovery in case of compromise. Stay informed on vendor communications and apply security patches promptly once available. Additionally, consider isolating the WooCommerce environment or using security plugins that enforce role-based access controls to mitigate privilege escalation risks.
