Same, same but different

MEV Boost, NFT fails etc, all these hacks were enabled by underlying technical vulnerabilities some of which can appear to the (un)trained eye very similar to classic vulnerabilities we see in web2. Are they or are we being flippant, only one way to find out.

So this is the one where we really dig into the technical details of the most well known vulnerabilities in web2 and web3 and decide whether there are actually any similarities at all.
