CVE-2025-2594 describes an authentication bypass vulnerability in the User Registration & Membership WordPress plugin prior to version 4.1.3. When the Membership Addon is enabled, insufficient data validation in an AJAX action allows unauthenticated attackers to log in as any user, including administrators, by providing a target user's ID. This vulnerability carries a high CVSS score of 8.1, indicating a critical risk due to its network-based attack vector, low attack complexity, and high impact on confidentiality, integrity, and availability. While not yet listed in CISA's KEV catalog, public exploit code (EDB-52302) exists, and the vulnerability has garnered significant community discussion, suggesting a high potential for exploitation.
