AI agents can unintentionally leak access tokens

AI agents that automate tasks for apps using access tokens—digital keys for third-party APIs—can accidentally leak those keys. Sensitive tokens often get copied into logs, error messages, or prompts as agents process instructions from untrusted sources, like tickets or uploaded documents. This isn't a coding flaw; it's just how agent systems work by design. The risk: automated requests can leak credentials without a breach.

Why it mattersIf you're using AI agents to automate workflows, your app's keys could end up somewhere they don't belong. That can open the door to unwanted access or abuse, even if no one hacks your system.
