CVE-2026-93327 · Severity: high · Published 2026-10-30

Google Application Integration is a cloud service that orchestrates business workflows and processes. A deserialization vulnerability in the SubWorkflow task allowed authenticated users to execute arbitrary code on the service by uploading malicious serialized objects. This could enable attackers with legitimate account access to compromise workflows, manipulate data, or pivot to other services.
