CVE-2026-16236Network attack vector

Subscriber-level arbitrary file upload via unvalidated images

Published Jul 31, 2026 · Updated Jul 31, 2026

Arbitrary file upload in Realtyna Organic IDX plugin + WPL Real Estate 5.3.0 and earlier allows remote authenticated users to upload files. The saveLiveImages() function accepts imported image data without checking file extensions or content, while get_keys() and the REST import route fail to enforce authentication and authorization. Subscriber-level access is sufficient to place arbitrary files on the server; code execution depends on the uploaded file being executable there.
