Summary

The Simple Membership WordPress plugin before 4.8.3 does not avoid transmitting a newly registered member's plaintext password in a URL query string when an optional auto-login-after-registration feature is enabled, exposing the credential in browser history and in web server, proxy, and CDN access logs to anyone able to read them.

Risk Assessment

Plaintext password leakage can lead to user account compromise and potential security breaches in other services if users reuse passwords.

Recommendation

Update the Simple Membership plugin to version 4.8.3 or later that includes security fixes. If not available, consider disabling the auto-login-after-registration feature.
