Summary

AshLua read operation aggregate bypasses the exposed-field allow-list, exposing private attributes

Details

Improper Protection of Alternate Path vulnerability in ash-project ash_lua allows a user-supplied Lua script to read attributes that are not on the exposed-field allow-list.

AshLua exposes Ash resources to Lua scripts, gated by a manifest declaring which fields are exposed. The read action's operation aggregate path in AshLua.Runtime took the field name straight from the Lua call and resolved it with only String.to_existing_atom and Ash.Query.Aggregate.new!, neither of which consults the exposed-field allow-list the normal fields path enforces. A script can therefore read the value of any attribute of any record the actor may read, including private sensitive?: true columns, via resource.read({ operation = {"list", "hashed_password"} }); min and max give a value oracle. Anyone able to submit or influence a Lua script can reach this.

This issue affects ash_lua: from 0.1.0 before 0.2.1.
