Description
Telenia Software TVox 26.5.3 and prior 26.x versions, and 24.9.21 and prior 24.x versions, contain an authentication bypass vulnerability in set_env.php where the redirectToLoginAdminIRequestHaveAccessToken() function derives the current page name from PHP_SELF and skips authentication when the value matches 'login_admin.php'. Attackers can append '/login_admin.php' to the path of any target PHP script to cause the authentication check to pass and gain unauthenticated access to all PHP scripts under the manager HTML directory.
Detection & mitigation playbook
VulnerabilityDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for the affected component. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
Remediation status
No patched version of the affected component has shipped for CVE-2026-64827 yet. Where your build allows, override or pin the dependency away from the vulnerable range, and apply any maintainer-recommended mitigation.
Mitigate without a patch
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 pinpoints whether CVE-2026-64827 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to CVE-2026-64827. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
