# CVE-2026-116800

> 6.9 MEDIUM · 🧪 PoC

## Beschreibung

WWBN AVideo before 29.5.0 contains a local file inclusion vulnerability that allows unauthenticated attackers to include PHP files outside the locale directory via a crafted Accept-Language header. Attackers can use overlapping traversal sequences like ....// to bypass single-pass removal in setLanguage(), executing existing server-side PHP files in the application context.

## Schwachstellen-Klasse

- **CWE-22** — Improper Limitation of a Pathname to a Restricted Directory
  The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory.
