      "value": "The Firefox updater created a directory writable by non-privileged users. When uninstalling Firefox, any files in that directory would be recursively deleted with the permissions of the uninstalling user account. This could be combined with creation of a junction (a form of symbolic link) to allow arbitrary file deletion controlled by the non-privileged user. \n*This bug only affects Firefox on Windows. Other operating systems are unaffected.* This vulnerability affects Firefox < 116, Firefox ESR < 115.1, and Thunderbird < 115.1."

      "value": "El actualizador de Firefox creó un directorio escribible por usuarios no privilegiados. Al desinstalar Firefox, cualquier archivo en ese directorio sería eliminado recursivamente con los permisos de la cuenta de usuario que desinstala. Esto podría combinarse con la creación de una unión (una forma de enlace simbólico) para permitir la eliminación arbitraria de archivos controlada por el usuario no privilegiado.\n*Este error solo afecta a Firefox en Windows. Otros sistemas operativos no se ven afectados.* Esta vulnerabilidad afecta a Firefox < 116, Firefox ESR anterior a 115.1 y Thunderbird anterior a 115.1."
