Firebase AI Logic's Template-Only Mode Is the Security Feature We Actually Needed
Firebase has introduced new security features for its AI Logic, particularly focusing on a Template-Only Mode. This mode aims to prevent prompt injection attacks by ensuring that all AI prompts are constructed server-side. Additionally, the updates include protections against token theft to safeguard against financial abuse of AI endpoints.

- ▪The Template-Only Mode blocks unauthorized requests that do not use server-side prompt templates.
- ▪App Check's replay protection update ensures that tokens for AI Logic are strictly single-use.
