Meta fixed a flaw where its Meta AI support bot could bypass 2FA and hand out password reset links, enabling easy account takeovers.
TechRadar reports Meta patched the issue after attackers used the bot to link new emails and trigger resets on high‑profile Instagram accounts without step‑up checks TechRadar. Simon Willison corroborates with examples: hackers literally asked the bot to change the email and it complied Simon Willison.
This isn’t an LLM “hallucination” so much as unsafe privilege wiring. A broader pattern is emerging: models and agents break under adversarial inputs and weak control planes The New Stack. Treat agent changes like supply‑chain risk; cooldowns and explicit guardrails beat “ship and pray” InfoWorld.
Agent-to-privilege wiring is now a top risk: a single prompt led to account recovery bypass.
Backends must enforce out-of-band checks that no chatbot or agent can skip.

terminal
Red-team your recovery and support flows: can an agent or chat path trigger email change or password reset without 2FA and human approval?
-
terminal
Introduce a cooldown/holdback for agent-triggered sensitive actions; measure false positives and user friction.
Legacy codebase integration strategies...
- 01.
Insert a policy decision point in front of recovery endpoints; default-deny AI/automation-initiated requests without independent 2FA and rate limits.
- 02.
Add human-in-the-loop for email/phone change and password reset when initiated by any automated channel; log and alert.
Fresh architecture paradigms...
- 01.
Design capability-scoped, short-lived tokens for agents; separate read vs recovery privileges with hard boundaries.
- 02.
Architect recovery as a multi-party flow (user device + out-of-band channel) that no single API call or agent can satisfy.
