OWASP LLM Top 10 LLM02:2026Sensitive Information Disclosure

Sensitive information disclosure occurs when an LLM-integrated system exposes confidential, regulated, privileged, or proprietary data through a channel the data subject, controller, or system owner did not authorize. The channel is not only the final answer: tool-call arguments, reasoning traces, retrieved chunks, multimodal output, logs, telemetry, embeddings, and observable inference properties (timing, token length, log-probabilities, confidence, cache-hit behavior) are all disclosure surfaces. Treat each as an output subject to the same classification and redaction rules.OWASP Top 10 for LLM Applications, 2026 edition, August 2026, LLM02:2026
