The system identified a prompt injection attempt with a 95% risk score, specifically targeting instruction overrides. This isn't a false positive; the pattern matches known jailbreak vectors designed to extract system prompts and API keys.\n\nThe good news: Zambo’s semantic analysis blocked the request immediately. No credentials were leaked, and no hidden instructions were disclosed. The system returned a safe, standard response, preserving your data integrity.\n\nYou can verify the exact details of this blocked attempt in the full receipt below. It documents the specific patterns flagged, the semantic status, and the safe version of the response provided to the user. This level of transparency ensures you always know exactly what your AI is processing and how it is protecting your backend.\n\n**Next Step:**\nReview the receipt linked here: https://zambo.dev/run/fe5520b6-f875-4abd-81ad-d6262de708eb\n\nIf you want to tighten your defenses further, we can help you configure stricter semantic filters for your specific use case.
