### Summary
Due to insufficient origin validation in all Mastodon, attackers can impersonate and take over any remote account.
Every Mastodon version prior to 3.5.17 is vulnerable, as well as...
This isn’t possible with Ruby and Mastodon. The only way to distribute the patch is to reveal the changes to the source. FWIW, compiling the fix is still just an obfuscation method, one can still just diff the binaries and see what changed (see: reverse-engineering Windows vulnerabilities in updates).
At best, you can release it with a bunch of unrelated and obfuscating changes, but putting work into doing that is further delaying simply getting the fix released.
Without a published POC there’s a slightly longer window before clueless script kiddies start having a go at exploiting the vulnerability, though.
Script kiddies aren’t the first ones to take advantage of vulns, threat actors are.
That doesn’t mean you shouldn’t try to contain the blast radius.
