Summary

The Essential Real Estate WordPress plugin before 5.3.6 does not verify that the recipients it allows for its contact email action are legitimate, allowing users with the self-registered Customer role to add any address to that allowlist so that unauthenticated users can then send emails with attacker-controlled content to it through the site.
