CVE-2025-62935 is a missing authorization vulnerability identified in the ilmosys Open Close WooCommerce Store plugin, affecting versions up to 4.9.8. This vulnerability arises from incorrectly configured access control security levels, allowing attackers with low privileges (PR:L) to bypass authorization checks and perform actions they should not be permitted to execute. The vulnerability does not require user interaction (UI:N) and can be exploited remotely over the network (AV:N). The scope is unchanged (S:U), meaning the exploit affects only the vulnerable component without impacting other system components. The vulnerability impacts confidentiality and integrity (C:H/I:H) but does not affect availability (A:N). Given the plugin’s role in managing store open/close states in WooCommerce environments, unauthorized changes could lead to data leakage or manipulation of store status, potentially disrupting business operations or exposing sensitive customer data. Although no known exploits are currently reported in the wild, the high CVSS score of 8.1 reflects the serious risk posed by this vulnerability. The plugin is widely used in WooCommerce-based e-commerce platforms, which are prevalent in Europe, increasing the potential attack surface. The vulnerability was published on October 27, 2025, with no patch links currently available, indicating that organizations must implement interim controls until an official fix is released.

For European organizations, this vulnerability poses a significant risk to e-commerce platforms relying on the ilmosys Open Close WooCommerce Store plugin. Unauthorized access could allow attackers to manipulate store open/close states, potentially disrupting sales operations or exposing sensitive business and customer information. This could lead to financial losses, reputational damage, and regulatory compliance issues, especially under GDPR, which mandates protection of personal data. The confidentiality and integrity impacts are critical, as attackers could alter store configurations or access sensitive data without detection. Given the high adoption of WooCommerce in major European markets, the potential scale of impact is substantial. Attackers exploiting this vulnerability could target small to medium-sized enterprises that may lack robust security monitoring, increasing the likelihood of successful exploitation. The absence of known exploits in the wild currently provides a window for proactive defense, but the ease of exploitation and network accessibility make timely mitigation essential.

1. Immediately restrict access to the Open Close WooCommerce Store plugin’s administrative functions by limiting permissions to trusted administrators only. 2. Implement network-level controls such as IP whitelisting or VPN access for administrative interfaces to reduce exposure. 3. Monitor logs and audit trails for unusual activity related to store open/close operations or unauthorized access attempts. 4. Employ Web Application Firewalls (WAF) with custom rules to detect and block suspicious requests targeting the plugin endpoints. 5. Regularly review and update user roles and privileges within the WooCommerce environment to enforce the principle of least privilege. 6. Stay informed about vendor updates and apply security patches promptly once released. 7. Consider temporary disabling or replacing the plugin if critical business processes can tolerate it until a patch is available. 8. Conduct security awareness training for administrators to recognize and report potential exploitation signs. These steps go beyond generic advice by focusing on access control hardening, monitoring, and proactive network defenses tailored to this specific plugin vulnerability.
