Security update - two major vulnerabilities found
Motivated by this week’s discovery of a security vulnerability, we analysed the entire Umbraco core and found two additional major vulnerabilities
Just now, Shannon stumbled upon a bug in the recent 4.10.0 release, that exposes a security issue.
This security problem ONLY affects installs of 4.10.0 and is easily fixed by downloading the patch file on CodePlex to upgrade your site to 4.10.1.
How to upgrade:
We've update the version checker so anybody running 4.10.0 should see an upgrade message soon.
We urge everybody with a 4.10.0 site to upgrade to 4.10.1 as soon as possible. Versions OTHER than 4.10.0 are NOT affected at all, so you won't need to take any action for those.
Our sincere apologies for the incovenience!
