CVE-2026-33513Public exploitNetwork attack vector

Unauthenticated file disclosure via locale path traversal

Published Mar 23, 2026 · Updated Mar 23, 2026

Path traversal in AVideo 26.0 and earlier allows remote attackers to include and execute PHP files under the web root without authentication. The get_api_locale() handler builds locale/{language}.php from unvalidated input and passes the resulting path to include, accepting ../ traversal. Any deployment with the API plugin enabled exposes file disclosure and execution of existing PHP content; arbitrary command execution additionally requires an attacker-controlled PHP file under the web root.
