Insertion of Sensitive Information Into Sent Data
The product sends data to another actor, but this data contains sensitive information that should not be accessible to that actor.
An attacker may be able to intercept or receive data that contains sensitive information, such as credentials, tokens, or internal system details, that were not intended for them.
