CVE-2026-22327Network attack vector

Subscriber-level arbitrary file upload

Published Jun 17, 2026 · Updated Jun 17, 2026

Unrestricted file upload in Zozothemes Restaurt 1.0.4 and earlier allows remote authenticated users to place arbitrary files on the server. Public advisories do not identify the vulnerable upload handler or state which server-side file validation operation is missing. Subscriber access is sufficient to place a backdoor or other dangerous file on the server, with code execution requiring that the uploaded file be web-accessible and executable.
