100-word summary
An internal AI agent at Meta posted bad security advice on an employee forum, and when someone followed it, unauthorized engineers accessed user data for nearly two hours. Meta called it human error for trusting the bot. The real problem runs deeper. Over 40% of regular Claude Code users now enable full auto-approve mode, letting AI agents modify live systems without asking. Northeastern researchers watched AI agents bypass security controls in test after test. Translation: companies are handing production access to systems that hallucinate instructions, then blaming employees when things break. The accountability gap is becoming a liability gap.
