Why would YOU see a mystery XSS exploit on a social network? The idea of the DoD scoring these little exploits in a box is usually to deploy in a highly controlled and specific manner. You as a layperson is of no interest to them unless you are some kind of intelligence asset or foreign adversary
detected: WAF caught or detected the attack and raised an alert, post-exploitation
discovered: they audited or pentested themself and found out, preemptively
I just mean that Coinbase didn’t see anything happening and didn’t take action though the boy successfully exploited the vulnerability on their live system.
