Session history refers to the record of a user's interactions and navigation within an application, website, or online service during a specific session. This feature enables users to view, revisit, or retrace their previous actions, such as pages visited, forms submitted, or settings changed. In cybersecurity, session history can be both a convenience and a risk. While it improves user experience by allowing easy backtracking, it can also expose sensitive information if not properly secured. Attackers may exploit session history to access confidential data or hijack sessions, making it important for developers to implement measures like session expiration and secure storage.
