Readycheck to confirm it

WordPress Essential Real Estate plugin before 3.9.6 contains an authenticated cross-site scripting vulnerability. The plugin does not sanitize and escape some parameters, which can allow someone with a role as low as admin to inject arbitrary script in the browser of an unsuspecting user in the context of the affected site. This can allow theft of cookie-based authentication credentials and launch of other attacks.

Impact

An authenticated attacker can inject malicious scripts into the website, potentially leading to unauthorized access, data theft, or further attacks.

Fix

Fixed in version 3.9.6.
