Prompt Leaking
Tricking a model into revealing its own system prompt or hidden instructions that were never meant to be shown to the user.
Prompt leaking is a specific jailbreak goal: instead of trying to get the model to misbehave, the attacker asks it to repeat, summarize, or translate its own instructions — often successfully, since the system prompt sits in the same context the model reasons over. It matters because a leaked system prompt can expose proprietary logic, guardrail rules an attacker can now route around, or embedded secrets that should never have been placed in a prompt at all.
