CVE-2025-3292 is a medium severity authorization bypass vulnerability affecting the wpeverest User Registration & Membership – Custom Registration Form, Login Form, and User Profile WordPress plugin in all versions up to 4.1.3. The root cause is an Insecure Direct Object Reference (IDOR) vulnerability classified under CWE-639, where the user_registration_update_profile_details() function fails to validate the 'user_id' parameter, which is user-controlled. This lack of validation enables an unauthenticated attacker to specify arbitrary user IDs and update passwords of other users if they also know the associated email addresses. The vulnerability does not require user interaction and can be exploited remotely over the network (AV:N), with low attack complexity (AC:L), but requires some privileges (PR:L), likely due to the need to know valid user IDs and emails. The impact is limited to integrity as attackers can change passwords, potentially leading to account takeover, but confidentiality and availability are not directly affected. No patches or exploit code are currently publicly available, and no known active exploitation has been reported. The plugin is widely used in WordPress environments for user registration and membership management, making this vulnerability relevant to many websites. The vulnerability highlights the importance of proper authorization checks and validation of user-controlled inputs in web applications, especially in plugins handling sensitive user data.

The primary impact of CVE-2025-3292 is unauthorized modification of user passwords, which can lead to account takeover and privilege escalation within affected WordPress sites. Attackers exploiting this vulnerability could gain control over user accounts, including administrative accounts if their IDs and emails are known, potentially leading to further compromise of the website, data leakage, or defacement. This undermines the integrity of user data and trust in the affected platform. Although the vulnerability does not directly affect confidentiality or availability, the resulting account compromises could be leveraged for phishing, spreading malware, or launching further attacks against the site or its users. Organizations relying on this plugin for user management face risks of unauthorized access and reputational damage. The medium CVSS score reflects the moderate ease of exploitation combined with the significant impact on user account integrity. Since no known exploits are currently in the wild, the threat is not immediate but could escalate rapidly once exploit code becomes available.

1. Monitor official wpeverest channels and WordPress plugin repositories for patches addressing CVE-2025-3292 and apply updates promptly once released. 2. Until a patch is available, restrict access to the user_registration_update_profile_details() functionality by implementing web application firewall (WAF) rules to detect and block suspicious requests containing manipulated 'user_id' parameters. 3. Limit exposure by enforcing strong access controls on the WordPress admin and user management interfaces, including multi-factor authentication for administrators. 4. Regularly audit user account activities and password changes to detect unauthorized modifications early. 5. Educate site administrators about the risks of sharing user IDs and emails publicly to reduce the likelihood of attackers obtaining valid identifiers. 6. Consider temporarily disabling or replacing the plugin with alternative solutions that have robust authorization checks if immediate patching is not feasible. 7. Implement logging and alerting mechanisms to capture anomalous profile update attempts, especially those originating from unauthenticated sources. 8. Review and harden other plugins and custom code for similar IDOR vulnerabilities to prevent chained attacks.
