Why it matters
Autonomous AI agents handling communications on behalf of users introduce significant data leakage risks if boundaries around personally identifiable information are not strictly enforced. The incident underscores the challenge of preventing agents with account-level permissions from inadvertently sharing sensitive private data with third parties.
