I’m seeing this topic just now. The version of the xblock that ships with Olive is 4.5.0. Is version 4.5.0 affected by the vulnerability? If yes, can we safely upgrade to 7.2.2? In my understanding there are at least three breaking changes between 4.5.0 and 7.2.2, so it seems unlikely that we can upgrade without any problem in Olive.
