Gemini Enterprise Agent Platform App Builder
Monthly
Server-Side Request Forgery in Google Cloud Gemini Enterprise Agent Platform App Builder (all versions prior to the 2026-06-01 deployment date) enables unauthenticated remote attackers to exfiltrate the Compute Engine default service account access token by forcing the application to issue requests to the GCP instance metadata service. The stolen OAuth 2.0 bearer token carries the IAM permissions of the default service account, potentially enabling lateral movement across GCP project resources. Vendor-released patch was deployed on 1 June 2026, but existing app deployments require a manual redeployment to receive the fix - creating remediation lag risk for unmanaged deployments.
