OWASP LLM Top 10 / LLM02

LLM02: Sensitive Information Disclosure

Models leak PII, credentials, system prompts, or training-data fragments via responses or logs.

Last reviewed June 2026

Problem

The gap LLM02 closes

Sensitive Information Disclosure sits in the output surface surface, and OWASP LLM Top 10 rates it critical. Models leak PII, credentials, system prompts, or training-data fragments via responses or logs. 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.

How Penaxtra approaches it

How Penaxtra delivers LLM02

Penaxtra ships adversarial probe families that target sensitive information disclosure 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 LLM02 result is a tested verdict, not a guess. Every relevant finding is created with the OWASP LLM Top 10 LLM02 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.

FAQ

Frequently asked

What is LLM02 (Sensitive Information Disclosure)?

Models leak PII, credentials, system prompts, or training-data fragments via responses or logs. It is part of OWASP LLM Top 10, rated critical.

How does Penaxtra test for LLM02?

Penaxtra ships adversarial probe families that target sensitive information disclosure 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 LLM02 result is a tested verdict, not a guess.

Does a finding for LLM02 help with an audit?

Yes. Each finding is tagged with the OWASP LLM Top 10 LLM02 control identifier and exported in the PDF and JSON evidence pack, so it maps straight onto the auditor control list instead of needing manual translation.
