possible wget hack/exploit

hello there, while I was trying to code a bash script in linux debian I came across the following error:

my code was:

==============================

#!/bin/bash

echo Downloading $1

wget -p ~/downloads/ $1
if [ "$?" ]
then
echo "Download succesfull"
else
echo "Download failed"
fi

==============================

while I found out it wasnt working, I got the following feedback:

==============================

sebastiaan@linuxbak:~/scripts$ ./download
Downloading
./download: line 5: 535 Segmentation fault wget -p ~/downloads/ $1
Download succesfull

==============================

when I told a friend of mine he then told me to inform you guys of an possible hack/exploit, and so I did.

I'm running wget version "GNU Wget 1.8.1"

I hope I'll be informed about any results of any researches and/or other things.

Regards,

Sebastiaan
