RISK

Why GOOGLESUPER_GET_ATTACHMENT is rated Low

This tool retrieves email attachments without side effects, fitting the Read category. However, severity is medium rather than low because attachments can contain sensitive information (financial documents, personal files, credentials), and unauthorized access via a compromised AI agent could expose confidential data.

From the tool's definition Tool name 'GET_ATTACHMENT' and description 'Retrieves a specific attachment' indicate a read operation that queries and fetches data from Gmail without modification.
