CVE-2026-89242Public exploitNetwork attack vectorHinoki check available

Local file read via unvalidated JSON source

Published Sep 11, 2026 · Updated Sep 15, 2026

Server-side request forgery in WWBN AVideo allows remote attackers to read local files and access internal services. The objects/login.json.php endpoint passes the unauthenticated request body to _json_decode(), which uses file_get_contents() on accepted URLs or paths without SSRF validation. Exposure requires network access to the login endpoint; a crafted body can load JSON from loopback services or permitted local paths into the login parameter bag.
