Description
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.

Executive Summary

The Essential Real Estate WordPress plugin before version 5.3.6 has a flaw where it does not check if email recipients added to its contact email allowlist are legitimate. This lets users with the self-registered Customer role add any email address to the list. Unauthenticated attackers can then send emails with malicious content through the site using these addresses.

Detection Guidance

Check the installed version of the Essential Real Estate WordPress plugin. If it is version 5.3.5 or below, the system is vulnerable. Use commands like 'wp plugin list' in WordPress CLI or inspect the plugin files directly.

Impact Analysis

This vulnerability allows attackers to send phishing emails or spam from your website, potentially damaging your reputation. It could also be used to distribute malware or deceive users into revealing sensitive information. If your site uses the Essential Real Estate plugin version 5.3.5 or earlier, it is at risk.

Compliance Impact

This vulnerability could lead to unauthorized email transmissions, potentially violating data protection regulations like GDPR or HIPAA if sensitive data is exposed. Non-compliance may result in legal penalties or reputational damage.

Mitigation Strategies

Update the Essential Real Estate plugin to version 5.3.6 or later immediately. Remove or restrict the self-registered 'Customer' role permissions if possible. Monitor for unauthorized email activity.
