CVE-2025-49265 is a high-severity vulnerability classified under CWE-862 (Missing Authorization) affecting the WordPress plugin 'Membership For WooCommerce' developed by WP Swings. This vulnerability arises due to insufficient access control mechanisms, allowing unauthorized users to access functionality that should be restricted by Access Control Lists (ACLs). Specifically, the flaw permits unauthenticated remote attackers to invoke certain functions or access features without proper authorization checks. The affected versions include all versions up to and including 2.8.1, with no specific lower bound version identified. The CVSS v3.1 base score of 7.5 reflects a network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:N), and no user interaction needed (UI:N). The impact is limited to confidentiality, with no integrity or availability impact reported. This means attackers can potentially access sensitive membership or user data managed by the plugin without authentication, but cannot modify data or disrupt service availability. No known exploits are currently reported in the wild, and no patches have been linked yet. The vulnerability was reserved and published in early June 2025, indicating a recent discovery. The plugin is widely used in WooCommerce environments to manage membership-based access and subscriptions, making this vulnerability significant for e-commerce sites relying on membership gating for premium content or services.

For European organizations, especially those operating e-commerce platforms using WooCommerce with the Membership For WooCommerce plugin, this vulnerability poses a serious risk to the confidentiality of customer and membership data. Unauthorized access could lead to exposure of sensitive user information, membership statuses, or premium content, potentially resulting in privacy violations under GDPR regulations. Although the vulnerability does not allow data modification or service disruption, the leakage of confidential membership data could damage customer trust and lead to regulatory penalties. Organizations in sectors such as retail, digital media, education, and subscription services that rely on membership gating are particularly vulnerable. The ease of exploitation (no authentication or user interaction required) increases the likelihood of automated scanning and exploitation attempts. Given the high adoption of WooCommerce in Europe, the threat could be widespread if not mitigated promptly.

1. Immediate mitigation should include disabling or removing the Membership For WooCommerce plugin until a security patch is released. 2. Monitor official WP Swings channels and Patchstack advisories for updates or patches addressing CVE-2025-49265. 3. Implement Web Application Firewall (WAF) rules to restrict or block suspicious requests targeting membership-related endpoints, especially those that could invoke unauthorized functions. 4. Conduct thorough access control audits on WooCommerce membership functionalities to identify and remediate any other potential authorization weaknesses. 5. Limit exposure by restricting administrative and membership management interfaces to trusted IP ranges or VPN access where feasible. 6. Review and enhance logging and monitoring to detect unusual access patterns or unauthorized data access attempts. 7. Educate site administrators about the vulnerability and encourage prompt updates once patches are available. 8. Consider alternative membership management plugins with verified security postures if immediate patching is not possible.
