CVE-2026-16236
No known patch is available for this vulnerability.
The affected plugin has been removed from the WordPress.org directory, and no patched version is being distributed through the official directory. If you have the affected software installed, you should uninstall or replace it rather than wait for an update.
Description
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.
