There's non/offtopic breaks, such as host and user security.
False breaks, such as with documented design weaknesses... eg: timing.
And real breaks, such as 0-day against the daemon, protocol, or unknown
design weaknesses.

There are plenty of the first.
Few of the second, outside of the attack classes you'd find in the anonbib.
And hopefully any of the third have already made it to the changelog or

Does anyone recall a time in the past where a client or service was
actually at real risk due to something from the third?

Might as well add drugs to the OP's list. Those major services (eg: silkroad)...
a) have already been found and are still operating under whatever scheme
you wish
b) are impossibly (perhaps quite unbelievably) hard to find
c) are still there because no one's bothered to look, yet

Some might consider locking down their guards.
Though if up against a PA that can watch them, that doesn't matter either.
Seems everyone's waiting for the canaries...
