Any authenticated user holding asset-read access could therefore enumerate asset events \u2014 including the source Dag ID, task ID, run ID and event timestamps \u2014 for Dags they have no permission to see. Because the filter was also absent from the count query, `total_entries` and pagination disclosed the existence of hidden Dags even without inspecting individual rows. Deployments are affected whenever per-Dag access control is used to separate teams or tenants; no special configuration is required.
