CVE-2026-64827Public exploitNetwork attack vector

Unauthenticated manager access via PHP_SELF path spoofing

Published Aug 3, 2026 · Updated Aug 3, 2026

Authentication bypass in Telenia Software TVox 24.0.0 through 24.9.21 and 26.0.0 through 26.5.3 allows remote attackers to access manager scripts. redirectToLoginAdminIRequestHaveAccessToken() derives the page name from attacker-controlled PHP_SELF and exempts login_admin.php from authentication. Appending /login_admin.php to a target script path satisfies that exemption without credentials, exposing every PHP script under the manager HTML directory.
