CVE-2026-48745
Traccar Client: silent configuration hijack via unverified deep link redirects all GPS telemetry
Description
Traccar Client is a GPS tracking mobile app for sending location updates to private servers using the open-source Traccar platform. In versions 9.7.19 and below, a single crafted deep link can silently hijack all GPS tracking parameters and redirect telemetry to an attacker-controlled server. The app registers a custom org.traccar.client://config deep-link scheme that silently writes attacker-supplied parameters (server URL, device ID, accuracy, distance, and interval) into the app's persistent configuration with no confirmation, notification, or visual indication. A single crafted link delivered via SMS, email, a webpage, or any installed app can therefore reconfigure the app the moment the victim taps it, with no special permissions required. As a result, an attacker can covertly redirect all of the victim's GPS telemetry to their own server at maximum precision and frequency, and the change persists across restarts. This gives the attacker continuous, real-time tracking of the victim's location. This issue has been fixed in version 9.7.20.

Action Type Old Value New Value Added Translation Title: traccar-client de traccar, Description: Traccar Client es una aplicación móvil de seguimiento GPS para enviar actualizaciones de ubicación a servidores privados utilizando la plataforma de código abierto Traccar. En las versiones 9.7.19 e inferiores, un único deep link malicioso puede secuestrar silenciosamente todos los parámetros de seguimiento GPS y redirigir la telemetría a un servidor controlado por el atacante. La aplicación registra un esquema personalizado de deep link org.traccar.client://config que escribe silenciosamente parámetros proporcionados por el atacante (URL del servidor, ID del dispositivo, precisión, distancia e intervalo) en la configuración persistente de la aplicación sin confirmación, notificación o indicación visual. Un único enlace malicioso entregado a través de SMS, correo electrónico, una página web o cualquier aplicación instalada puede, por lo tanto, reconfigurar la aplicación en el momento en que la víctima lo toca, sin necesidad de permisos especiales. Como resultado, un atacante puede redirigir encubiertamente toda la telemetría GPS de la víctima a su propio servidor con la máxima precisión y frecuencia, y el cambio persiste a través de los reinicios. Esto le da al atacante un seguimiento continuo y en tiempo real de la ubicación de la víctima. Este problema ha sido solucionado en la versión 9.7.20. -
