CVE-2025-62005 is a Cross-Site Request Forgery (CSRF) vulnerability identified in the SUMO Memberships plugin for WooCommerce developed by FantasticPlugins. The vulnerability affects all versions prior to 7.8.0. CSRF vulnerabilities allow attackers to induce authenticated users to submit malicious requests unknowingly, potentially causing unauthorized actions on their behalf. In this case, the vulnerability can be exploited remotely without any authentication or privileges, but requires the victim to interact with a crafted malicious link or webpage. The CVSS 3.1 base score is 7.1, indicating high severity, with the vector AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:L/A:N. This means the attack can be performed over the network with low attack complexity, no privileges required, but user interaction is necessary. The impact on confidentiality is high, as attackers may be able to access or exfiltrate sensitive membership data or user information. Integrity impact is low, meaning some unauthorized changes might be possible but limited, and availability is not affected. No patches or exploit code are currently publicly available, but the vendor is expected to release a fix in version 7.8.0 or later. The vulnerability is particularly concerning for e-commerce sites using WooCommerce with SUMO Memberships, as membership data and user credentials are sensitive assets. Attackers could leverage this vulnerability to escalate privileges or extract confidential information by tricking users into executing unintended actions.

For European organizations, especially those operating e-commerce platforms using WooCommerce with the SUMO Memberships plugin, this vulnerability poses a significant risk to the confidentiality of customer and membership data. Unauthorized actions triggered by CSRF could lead to leakage of sensitive personal information, membership details, or even unauthorized changes to user accounts. This could result in reputational damage, regulatory penalties under GDPR for data breaches, and financial losses. The requirement for user interaction means phishing or social engineering campaigns could be used to exploit this vulnerability. The lack of authentication requirement lowers the barrier for attackers, increasing the threat landscape. Organizations relying heavily on membership-based services or subscription models are particularly vulnerable. The absence of known exploits in the wild currently reduces immediate risk but does not eliminate the potential for future attacks once exploit code becomes available.

1. Immediately monitor for updates from FantasticPlugins and apply the patch for SUMO Memberships version 7.8.0 or later as soon as it is released. 2. Implement or verify the presence of anti-CSRF tokens in all forms and state-changing requests within the WooCommerce environment and the SUMO Memberships plugin. 3. Restrict administrative access to trusted IPs or networks and enforce strong multi-factor authentication to reduce the risk of compromised credentials being exploited. 4. Educate users and administrators about phishing and social engineering tactics to reduce the likelihood of successful user interaction exploitation. 5. Employ web application firewalls (WAF) with custom rules to detect and block suspicious CSRF attack patterns targeting the plugin endpoints. 6. Regularly audit and monitor logs for unusual activity indicative of CSRF exploitation attempts. 7. Consider isolating or segmenting membership management functions to limit the blast radius of potential attacks.
