I deleted an earlier version of this post because it had mangled formatting, but there was already one comment, which I'm attaching here without attribution unless the author would like to claim it:

Which is why the base supply/transactions should be transparent.

"The vulnerability was present from Orchard's activation in May 2022 until the emergency fix was deployed on June 1, 2026."

"Because of the privacy properties of Orchard, there is no way to cryptographically prove whether the vulnerability was exploited before it was remediated."

And there's no way to 100% know whether someone  exploited/used it although they don't think so...
