Summary

The Estatik Real Estate Plugin WordPress plugin before 4.3.3 does not properly enforce its anti-spam check or restrict the recipient routing of its property request form. This allows unauthenticated users to send emails to arbitrary recipients with arbitrary subject, body and Reply-To, effectively using the site as a mail relay for spam or phishing.

Risk Assessment

The site can be used to send spam or phishing emails, potentially harming domain reputation and leading to email blacklisting.

Recommendation

Update the Estatik Real Estate Plugin to version 4.3.3 or later. Additionally, implement additional anti-spam mechanisms and restrict the ability to send emails to external recipients.
