Users can restore plugin's configuration by uploading a backup .ini file in the section \"Tool > Import/Export\". However, the plugin attempts to unserialize values of the .ini file. Moreover, the plugin embeds Monolog library which can be used to craft a gadget chain and thus trigger system command execution."
