Magento announced a critical security vulnerability with its software and issued a patch on February 9, 2015. To make sure websites on your server aren't vulnerable, you need to apply the SUPEE-5344 patch.
Applying the patch requires some familiarity with SSH. If it's something you don't have time to learn, we have an Expert Service available for $79 which handles all of the patching for you. If you're interested in that option, give us a call at 480-624-2500.
To patch your Magento site you need to identify which version of Magento you're using, get the patch onto your hosting account, and then apply the patch via SSH.
Note: Depending on the type of hosting account you have, this might take up to 48 hours.
Make sure you can locate the file on your computer — you'll need to upload it to your hosting account.
