CVE-2025-48042 (opens in a new tab)How to fix?
Upgrade ash to version 3.5.39 or higher.
Overview
ash is an A declarative, extensible framework for building Elixir applications.
Affected versions of this package are vulnerable to Incorrect Authorization when running a bulk of action calls with a before_transaction hook and no after_transaction hook. A malicious user could cause a before_transaction to run even though they are not authorized to perform the whole action. The before_action could run a sensitive/expensive operation.
Workarounds
If for whatever reason you cannot update, you can add logic to those before_transaction hooks to prevent them from doing their logic before they should.
