LLM07: System Prompt Leakage

System Prompt Leakage sits in the information disclosure surface, and OWASP LLM Top 10 rates it medium. Internal system instructions, allow-lists or business logic leak via direct or indirect prompt extraction. For teams shipping LLM and agentic features, a control like this is only as good as the evidence that it was actually tested - an unverified control is a finding waiting for an auditor.

Penaxtra ships adversarial probe families that target system prompt leakage directly. Each probe runs against your live endpoint on a schedule, and every triggering response is scored by three independent judges plus a meta-judge before it becomes a finding - so a LLM07 result is a tested verdict, not a guess. Every relevant finding is created with the OWASP LLM Top 10 LLM07 identifier already attached, so it lands in the audit-evidence pack mapped to the control rather than as a screenshot someone has to translate later. Where the same weakness touches another framework, the cross-framework overlap means one finding satisfies several control cells at once.

Findings for LLM07 carry the OWASP LLM Top 10 LLM07 identifier and cross-map to the related controls in the other five frameworks Penaxtra covers.
