FKIE_CVE-2026-23521

Vulnerability from fkie_nvd - Published: 2026-02-23 21:19 - Updated: 2026-02-26 16:27
Severity ?
6.5 (Medium) - CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N
Summary
Versions of the Traccar open-source GPS tracking system up to and including 6.11.1 contain an issue in which authenticated users who can create or edit devices can set a device `uniqueId` to an absolute path. When uploading a device image, Traccar uses that `uniqueId` to build the filesystem path without enforcing that the resolved path stays under the media root. This allows writing files outside the media directory. As of time of publication, it is unclear whether a fix is available.

Al cargar una imagen de dispositivo, Traccar utiliza ese \u0027uniqueId\u0027 para construir la ruta del sistema de archivos sin asegurar que la ruta resuelta permanezca bajo la ra\u00edz de medios. Esto permite escribir archivos fuera del directorio de medios. Al momento de la publicaci\u00f3n, no est\u00e1 claro si hay una soluci\u00f3n disponible."
