A recent study accepted to ASE 2026 found that a significant majority of credential leaks in AI agents stem from debug logging, not complex exploits. The research analyzed 17,022 third-party agent skills, revealing that 73.5% of credential leaks occurred because sensitive information was inadvertently printed to standard output, which is often piped directly into the model's context window and subsequently logged. This highlights tool output as a critical, often overlooked, leakage channel, prompting recommendations for better data hygiene, including secret redaction before output reaches the context window, capability-scoped and short-lived credentials, and rigorous vetting of agent skills.
