CVE-2023-47862Network attack vector

Unauthenticated code execution via Accept-Language file inclusion

Published Jan 10, 2024 · Updated Nov 4, 2025

Local file inclusion in WWBN AVideo commit 15fed957fb allows remote attackers to execute arbitrary code through crafted HTTP requests. The default User_Location path passes the first Accept-Language value through only tag stripping into setLanguage(), which includes the resulting locale path as PHP. No authentication is required, but code execution requires a malicious PHP file already present on the web server, such as one uploaded through a separate flaw.
