CVE-2026-78230Network attack vector

Protected-field disclosure via unauthorized aggregate queries

Published Sep 8, 2026 · Updated Sep 8, 2026

Insufficient access control in Ash AI before 1.0.3 allows remote authenticated users to read protected fields through aggregate queries. AshAi.Tool.Execution.execute_read/4 creates an ad hoc Ash.Query.Aggregate and returns its raw result after checking only that the named field is public, without enforcing the actor's field policy. Reachability requires an exposed Ash AI read tool, a public field restricted for the calling actor, and permission to invoke the tool.
