CVE-2026-35491

Name of the Vulnerable Software and Affected Versions Pi-hole FTL versions 6.0 through 6.5

Description Pi-hole FTL provides an interactive API and generates statistics for Pi-hole’s Web interface. Versions 6.0 through 6.5 contain an authorization bypass issue related to the Teleporter API. Specifically, the /api/teleporter endpoint allowed CLI-scoped sessions to overwrite configuration via a Teleporter archive, despite the /api/config endpoint correctly blocking CLI sessions from mutating configuration. This is due to the CLI password feature (webserver.api.cli pw) intended for read-only configuration changes.

Recommendations Update to version 6.6 or later.
