{
    "lastseen": "",
    "description": "Quark Drive before 0.8.5 contains a mass assignment vulnerability in the POST /update endpoint that allows authenticated attackers to overwrite administrator credentials by posting an arbitrary webui object to the config_data dictionary. Attackers can exploit insufficient deny-list filtering to permanently replace stored login credentials, lock out legitimate administrators, and gain persistent access to all configured tasks, cloud tokens, and notification services.",
