Description
CVE-2026-16236 is a high-severity vulnerability in the Realtyna Organic IDX plugin for WordPress, affecting versions up to and including 5.3.0. It allows authenticated users with subscriber-level access or higher to upload arbitrary files due to missing file extension and content validation, combined with insufficient authorization and authentication checks in certain plugin functions and endpoints. This arbitrary file upload could lead to remote code execution on the affected server.
