Worst bugs from LLM-generated code in production?


Let's hear about when these "magical" coding assistants actually burned you in production. Copilot, ChatGPT, Claude, whatever - what's the worst bug that made it past review and how much damage did it do?

Bonus points for security vulnerabilities and midnight incident reports.

Used Copilot to write a user auth migration script. It silently reset 2FA settings for ~3k users with OAuth accounts because it didn't handle NULL vs empty string edge cases in our legacy DB schema. Classic "garbage in, garbage out" situation.

Found out two weeks later when angry users couldn't log in during peak hours. Damage: 4 hours of downtime, one very grumpy security team, and a new "no AI for auth code" policy.
