CVE-2025-62935 is a security vulnerability identified in the ilmosys Open Close WooCommerce Store plugin, affecting all versions up to and including 4.9.8. The core issue is a missing authorization control, meaning that the plugin fails to properly verify whether a user has the necessary permissions before allowing certain actions. This misconfiguration of access control security levels can be exploited by attackers to perform unauthorized operations within the WooCommerce store environment. Since WooCommerce is a widely used e-commerce platform, this vulnerability could allow attackers to manipulate store open/close states or other critical functions managed by the plugin, potentially disrupting business operations or accessing sensitive store data. The vulnerability was reserved and published in late October 2025, but no CVSS score or official patch has been released yet, and no exploits have been observed in the wild. The lack of a patch and the nature of the vulnerability suggest that attackers with minimal privileges or unauthenticated users might exploit this flaw, increasing the risk. The vulnerability primarily impacts the confidentiality and integrity of the affected WooCommerce stores by allowing unauthorized access and control. Given the plugin’s role in store management, availability could also be indirectly affected if attackers disrupt store operations. The absence of authentication requirements and the broad scope of affected versions increase the threat surface. This vulnerability demands immediate attention from administrators of WooCommerce stores using the ilmosys plugin to prevent potential exploitation.

For European organizations, the impact of CVE-2025-62935 could be significant, especially for e-commerce businesses relying on WooCommerce with the ilmosys Open Close plugin. Unauthorized access could lead to manipulation of store operational states, unauthorized transactions, or exposure of sensitive customer and business data. This can result in financial losses, reputational damage, and regulatory compliance issues under GDPR due to potential data breaches. Disruption of store availability could also affect revenue streams and customer trust. Since WooCommerce is popular among small to medium enterprises across Europe, the vulnerability poses a broad risk. Attackers exploiting this flaw could gain control without authentication, making it easier to launch attacks at scale. The lack of a patch increases the window of exposure, and organizations may face targeted attacks once exploit code becomes available. The impact extends beyond individual stores to supply chains and partners relying on affected e-commerce platforms. Overall, the vulnerability threatens confidentiality, integrity, and availability of e-commerce operations in Europe.

European organizations should immediately audit their WooCommerce installations to identify if the ilmosys Open Close plugin is in use and confirm the version. Until a patch is released, restrict access to the plugin’s management interfaces by implementing strict role-based access controls and IP whitelisting where possible. Disable or remove the plugin if it is not essential to business operations. Monitor logs for unusual activity related to store open/close functions or unauthorized access attempts. Employ web application firewalls (WAF) with custom rules to detect and block suspicious requests targeting the plugin endpoints. Regularly check for updates from the vendor and apply patches promptly once available. Conduct internal penetration testing focusing on access control weaknesses in WooCommerce plugins. Educate staff on the risks of unauthorized plugin access and enforce the principle of least privilege for all users managing e-commerce platforms. Consider isolating critical e-commerce components in segmented network zones to limit lateral movement in case of compromise.
