Vulnerability Description
Authorization Bypass Through User-Controlled Key vulnerability in ash-project ash_ai allows a caller of an identity-configured tool to update or destroy records it never identified, including every row in the table. In AshAi.Tool.Execution, identity_filter/3 built the update/destroy filter directly from the raw tool arguments as [{key, Map.get(arguments, to_string(key))}] and passed it to Ash.Query.do_filter/2. A map value is parsed as a predicate expression rather than a literal, so a caller can send {"public_ref": {"not_eq": "<own-ref>"}} and, combined with Ash.Query.limit(1) and Ash.bulk_update!/Ash.bulk_destroy!, retarget the write at a record it never identified; an omitted key yields an IS NULL filter that matches an arbitrary row. The fix casts each identity value to the field type, rejecting non-scalar inputs. This issue affects ash_ai: from 0.6.0 before 1.0.0.
