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.

Pi-hole Admin Interface is a web interface for managing Pi-hole, a network-level ad and internet tracker blocking application. From 6.0 to before 6.5, a reflected DOM-based XSS vulnerability in taillog.js allows an unauthenticated attacker to inject arbitrary HTML into the Pi-hole admin interface by crafting a malicious URL. The file query parameter is interpolated into an innerHTML assignment without escaping. Because the Content-Security-Policy is missing the form-action directive, injected <form> elements can exfiltrate credentials to an external origin. This vulnerability is fixed in 6.5.
