Accidental exposure of classified information is commonly referred to as what?

The term used to describe the accidental exposure of classified information is network spillage. This occurs when classified data is unintentionally transferred to an unclassified system, making it accessible where it should not be. Network spillage is a critical concern in counterintelligence because it can lead to sensitive information being exploited by unauthorized individuals, thereby compromising national security.

This answer highlights the nature of the risk associated with mishandling classified information and underscores the importance of adhering to proper protocols to prevent such situations. Other terms mentioned, while related to information security, do not specifically address the inadvertent release or exposure of classified material.
