CVE-2026-82586Network attack vector

Private attribute disclosure via unchecked aggregate fields

Published Sep 7, 2026 · Updated Sep 8, 2026

Improper alternate-path protection in AshLua 0.1.0 through 0.2.0 allows attackers to read unexposed resource attributes via Lua scripts. AshLua.Runtime's read operation aggregate converts the caller-controlled field name and builds an Ash.Query.Aggregate without consulting the manifest allow-list. Reachability requires an application to expose AshLua scripting to a caller who can submit or influence scripts; successful access discloses any attribute on records the actor may read, including private sensitive columns.
