Executive Summary

This vulnerability affects the Simple Membership WordPress plugin before version 4.8.3. When the auto-login-after-registration feature is enabled, the plugin transmits a newly registered member's plaintext password in a URL query string. This exposes the password in browser history and server logs, including web servers, proxies, and CDNs.

Detection Guidance

Check WordPress plugin versions for Simple Membership. If using version before 4.8.3, the vulnerability may exist. Inspect web server, proxy, and CDN access logs for URLs containing plaintext passwords in query strings during registration.

Impact Analysis

If you use the affected plugin version, attackers with access to logs or browser history could steal plaintext passwords. This may lead to unauthorized account access, data breaches, or further exploitation of user accounts.

Compliance Impact

This vulnerability could violate GDPR and HIPAA requirements for protecting sensitive data. Exposure of plaintext passwords may result in unauthorized access to personal or health information, leading to compliance violations and potential legal penalties.

Mitigation Strategies

Update the Simple Membership plugin to version 4.8.3 or later immediately. Disable the auto-login-after-registration feature if not required. Review and sanitize access logs for any exposed credentials.
