CVE-2025-60222 is an Incorrect Privilege Assignment vulnerability found in the FantasticPlugins SUMO Memberships for WooCommerce plugin, affecting all versions up to 7.6.0. This vulnerability allows an attacker with low privileges to escalate their permissions within the WooCommerce membership system, potentially gaining administrative capabilities. The root cause lies in improper access control mechanisms within the plugin, which fail to correctly enforce privilege boundaries. The vulnerability is remotely exploitable over the network without requiring user interaction, increasing its risk profile. The CVSS v3.1 base score is 8.8, reflecting high impact on confidentiality, integrity, and availability, as an attacker could manipulate membership data, access sensitive customer information, or disrupt membership services. Although no public exploits are currently known, the widespread use of WooCommerce and this plugin in e-commerce environments makes this a critical issue. The vulnerability was reserved in late September 2025 and published in October 2025, indicating recent discovery and disclosure. The plugin’s role in managing memberships means exploitation could affect subscription management, payment processes, and user access controls, posing significant business risks.

For European organizations, the impact of CVE-2025-60222 is substantial due to the widespread use of WooCommerce in the region’s e-commerce sector. Exploitation could lead to unauthorized access to customer membership data, including personal and payment information, violating GDPR and other data protection regulations. Integrity of membership and subscription data could be compromised, leading to fraudulent access or manipulation of services. Availability disruptions could affect customer trust and revenue streams, especially for businesses relying on membership-based models. The breach of privileged access could also facilitate further lateral movement within affected networks, increasing the risk of broader compromise. Organizations in sectors such as retail, digital services, and subscription-based businesses are particularly vulnerable. The reputational damage and potential regulatory penalties from data breaches in Europe further amplify the threat’s impact.

1. Immediately restrict access to the SUMO Memberships plugin administration interfaces to trusted administrators only, using network-level controls or WordPress role hardening. 2. Monitor logs for unusual privilege escalation attempts or unauthorized access patterns related to membership management. 3. Apply any vendor-provided patches or updates as soon as they become available; if no patch exists yet, consider temporarily disabling the plugin or limiting its functionality. 4. Implement Web Application Firewall (WAF) rules to detect and block suspicious requests targeting the plugin’s endpoints. 5. Conduct a thorough audit of user roles and permissions within WordPress and WooCommerce to ensure least privilege principles are enforced. 6. Educate administrators about the vulnerability and encourage vigilance for phishing or social engineering attempts that could facilitate exploitation. 7. Prepare incident response plans specific to membership data compromise scenarios to enable rapid containment and remediation.
