Vertex Ai Search For Commerce
Monthly
Cross-tenant data exposure in Google Cloud Vertex AI Search for Commerce (versions prior to 2026-04-27) allowed an authenticated attacker who knew a victim's Google Cloud project number to read from and write to the Cloud Storage buckets used for BigQuery Import staging, because those bucket names were predictably derived rather than randomized. An attacker could reach another tenant's staged catalog data and import error logs, breaching data confidentiality and integrity across project boundaries. There is no public exploit identified at time of analysis, and Google fixed the issue server-side so no customer action is required.
