漏洞名称：wordpress WP_Image_Editor_Imagick 指令注入漏洞
在/wp-includes/media.php的_wp_image_editor_choose函数内部找到：
$implementations = apply_filters( 'wp_image_editors', array( 'WP_Image_Editor_Imagick' , 'WP_Image_Editor_GD' ) );
修改为
$implementations = apply_filters( 'wp_image_editors', array( 'WP_Image_Editor_GD' ,'WP_Image_Editor_Imagick' ) );
完成。
