I think the patches for the latest security issue with Magento has been installed, but I keep getting messages in the Admin area saying it is critical that I install the patches. Am I getting this messsage because the patch is not installed?
They are just that - messages. Everyone is getting them, including those that are patched.
Just shows how serious this one is, and how urgent it is to apply the patch.
I don't ever recall magento pushing out an alert to patch (but then I am growing old, so maybe I just forgot)
The site given by Thomas in the comments works great. If it says it is patched, it is patched.
