Summary

The CMP – Coming Soon & Maintenance WordPress plugin before 4.1.20 does not correctly restrict access to the site while maintenance/coming-soon mode is enabled, allowing unauthenticated visitors to bypass the coming-soon page and reach the otherwise hidden site, including hidden published pages, by shaping the request so it is mistaken for a login request.

Risk Assessment

Unauthorized individuals can access hidden site content, potentially disclosing information intended only for authorized users. This undermines the purpose of maintenance mode.

Recommendation

Update the CMP – Coming Soon & Maintenance plugin to version 4.1.20 or later. Verify that maintenance mode properly blocks access to all pages.
