Summary: Security researchers have uncovered two critical privilege escalation bugs in Google Vertex AI. The vulnerabilities allow low-privileged users to hijack the permissions of “Service Agents”—the automated identities used by the platform for model training—granting them unauthorized access to sensitive datasets, API keys, and internal cloud resources.
Business Impact: High risk of intellectual property theft. Attackers can use these “Service Agent” identities to silently exfiltrate proprietary training data or poisoned models. For your clients in Bahrain deploying AI, this is a “blind spot” in standard IAM (Identity and Access Management) auditing.
Why It Happened: The flaw involves a lack of sufficient permission boundaries between the “User” role and the “Auto-Managed Service Agent” role in the Vertex AI console, allowing for a token-exchange attack.
Recommended Executive Action: Audit all Vertex AI projects for excessive permissions assigned to Service Agents. Implement “Custom Service Identities” with restricted scopes rather than relying on the default project-level permissions.
