Data Leakage
Noun · Security & Infosec
Definitions
The unauthorized exposure or escape of sensitive data through technical flaws, misconfiguration, insecure handling, or accidental sharing. Leakage can happen without a dramatic breach if information quietly ends up in logs, public buckets, or third-party tools.
In plain English: Sensitive data getting exposed or shared when it should not be.
Example: "The root cause was data leakage through debug logs that captured full session tokens."
