CVE-2026-116800: WWBN AVideo local file inclusion in language code validation

CVE-2026-116800 · Severity: medium · CVSS 6.2 · Published 2026-10-27

WWBN AVideo is a video hosting and streaming platform. Before version 29.5.0, unauthenticated attackers could exploit a local file inclusion vulnerability in the language selection feature to execute arbitrary PHP files on the server. An attacker could leverage crafted Accept-Language headers to bypass path traversal protections and access sensitive files, potentially leading to remote code execution and data compromise.

Technologies: WWBN AVideo. Vendors: WWBN.

How to fix

  • Fixed in: AVideo 29.5.0

Technical details

The vulnerability exists in the setLanguage() function, which uses a single-pass str_replace() to remove '../' sequences from user-supplied language codes, allowing attackers to bypass this via overlapping traversal patterns like '....//'. An unauthenticated attacker can craft a malicious Accept-Language header to include PHP files outside the intended locale directory, executing arbitrary server-side code. Version 29.5.0 fixes this by implementing proper language code validation instead of simple string replacement.
