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 Website 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.
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.
