Just to illustrate a potential scenario:

You use a piece of open source software that has a javascript file which the author has hosted on a CDN. In order to mitigate an attack where someone changes the content of the javascript file you use a hash[1] to ensure the file does not change. You think you are safe, but a malicious actor gets access to the CDN and instead of changing the file, instead builds a quick scripts that looks for password reset referrer patterns and races the human to reset the password first. A computer is probably going to win that game that majority of the time.

Or the attack just skips the secure hash check on the server... This example doesn't seem to hold water either.
