Realtyna Organic IDX plugin + WPL Real Estate <= 5.3.0 - Authenticated (Subscriber+) Arbitrary File Upload
Strategic Overview
<= 5.3.0CVE-2026-16236Vulnerability Overview
The Realtyna Organic IDX plugin for WordPress is vulnerable to Arbitrary File Upload in versions up to, and including, 5.3.0. This is due to missing file extension and content validation in the saveLiveImages() function combined with an insufficient authorization check on the get_keys() AJAX handler and a missing authentication check on the REST API import endpoint. This makes it possible for authenticated attackers, with subscriber-level access and above, to upload arbitrary files on the affected site's server which may make remote code execution possible.
