Well this is pretty big. I just got this update from one of my security blogs HERE
In a nutshell, EOS is exploitable by allowing a remote attacker to take control of a node. If you can't picture how big of an issue this is, it's HUGE!!! Basically, this could discredit the network and anything built on/with it could fall victim to a 51% attack with relative ease.
Thankfully, this has been caught. However, I'd still anticipate some vulnerabilities with this. Industry standard is 5% of code has security vulnerabilities and flaws. EOS seems to be a HUGE project with a lot of code. So, as you can imagine, there's probably other existing flaws which will be discovered that hopefully won't impact the project and the usage.
Overall, I still think EOS is a great project and concept (even though I believe the EOS ERC20 token is garbage and y'all are crazy if you want to long term hold it). I'd love to see the improvements in EOS and the rest of the blockchain world.
Stay safe!
