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.

**Name of the Vulnerable Software and Affected Versions** Pi-hole Admin Interface versions 6.0 through 6.4 **Description** A reflected DOM-based XSS (Cross-Site Scripting) issue exists in `taillog.js`. An unauthenticated attacker can inject arbitrary HTML into the admin interface by crafting a malicious URL. This occurs because the `file` query parameter is interpolated into an `innerHTML` assignment without proper escaping. Additionally, the Content-Security-Policy lacks a `form-action` directive, which allows injected `<form>` elements to exfiltrate credentials to an external origin. **Recommendations** Update to version 6.5.
