Realtyna Organic IDX plugin + WPL Real Estate <= 5.3.0 - Unauthenticated Arbitrary File Upload via 'files[file]' Parameter via Public I/O 'set_property' Command
The Realtyna Organic IDX plugin + WPL Real Estate plugin for WordPress is vulnerable to Arbitrary File Upload in all versions up to, and including, 5.3.0 via the upload function. This is due to missing file type validation in the upload function, combined with a publicly accessible I/O endpoint authenticated solely by static, plugin-seeded API credentials that are identical across all installations. This makes it possible for unauthenticated attackers to upload files that may be executable, which makes remote code execution possible. The WPL I/O service endpoint is registered on the public WordPress init hook with no WordPress capability check, and the required api_key and api_secret values are static defaults seeded by the plugin's own SQL migration files, meaning any unauthenticated attacker who knows these publicly documented defaults can reach and exploit the vulnerable upload path.
