#8194 added the ability to pass URLs with queries around. And when someone else clicks the URL, the query is automatically populated in the sql editor and executed.
The issue here is, it's pretty common for someone to say "hey, can you help me with this < link to expensive query that takes down a server >?" And suddenly, you have a link in the wild that will slow or take down Pinot every time it's clicked even if they just wanted to see the query.
The proposal is to, by default, disable automatically running queries via URL (including back/forward buttons)
