CVE-2025-62005 is a Cross-Site Request Forgery (CSRF) vulnerability identified in the FantasticPlugins SUMO Memberships plugin for WooCommerce, affecting all versions prior to 7.8.0. CSRF vulnerabilities allow attackers to induce authenticated users to execute unwanted actions on a web application in which they are currently authenticated. In this case, the vulnerability permits an attacker to craft malicious web requests that, when visited by an authenticated user (such as an administrator), can alter membership configurations or perform other privileged operations without the user’s consent. The vulnerability has a CVSS v3.1 base score of 7.1, indicating high severity. The vector metrics are AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:L/A:N, meaning the attack is network-based, requires low attack complexity, no privileges, but does require user interaction. The impact on confidentiality is high, as unauthorized access or data leakage related to membership information is possible. Integrity impact is low, and availability is not affected. No known exploits have been reported in the wild, but the vulnerability is publicly disclosed and thus poses a risk. The plugin is widely used in WooCommerce-based e-commerce platforms to manage memberships, making the vulnerability relevant for online stores that rely on membership gating or subscription services. The lack of a patch link suggests that a fix may be pending or recently released. The vulnerability was reserved and published in October 2025, indicating recent discovery. Attackers could exploit this by sending a crafted link or embedding malicious code in a webpage that an authenticated user visits, triggering unauthorized actions on the vulnerable site. This type of attack can lead to unauthorized disclosure of membership data or unauthorized changes to membership status, potentially impacting business operations and customer trust.

For European organizations, especially those operating e-commerce platforms using WooCommerce with the SUMO Memberships plugin, this vulnerability poses a significant risk. Unauthorized changes to membership data can lead to exposure of sensitive customer information, unauthorized access to premium content or services, and potential financial losses. The confidentiality impact is particularly concerning for businesses handling personal data under GDPR regulations, as data breaches could result in regulatory penalties and reputational damage. The attack requires user interaction but no authentication, increasing the risk if users with administrative privileges are tricked into visiting malicious sites. The integrity impact, while lower, could still disrupt business processes by altering membership entitlements or subscription statuses. Availability is not impacted, so service disruption is unlikely. Given the widespread use of WooCommerce in Europe’s e-commerce market, the threat could affect a broad range of industries including retail, digital services, and membership-based organizations. The absence of known exploits in the wild reduces immediate risk but does not eliminate the threat, especially as public disclosure may prompt attackers to develop exploits.

Organizations should prioritize updating the SUMO Memberships plugin to version 7.8.0 or later as soon as the patch is available to remediate the vulnerability. Until an update can be applied, implement web application firewall (WAF) rules to detect and block suspicious CSRF attempts targeting membership-related endpoints. Enforce strict anti-CSRF tokens on all state-changing requests within the WooCommerce environment to prevent unauthorized cross-site requests. Limit administrative access to the WooCommerce backend by IP whitelisting or VPN access to reduce exposure. Educate administrators and privileged users about the risks of clicking on untrusted links or visiting unknown websites while logged into administrative sessions. Regularly audit membership and subscription changes for anomalies that could indicate exploitation attempts. Employ Content Security Policy (CSP) headers to reduce the risk of malicious script execution that could facilitate CSRF attacks. Monitor logs for unusual patterns of cross-site requests or membership modifications. Finally, maintain an incident response plan to quickly address any suspected compromise related to this vulnerability.
