ash is vulnerable to Incorrect Authorization
21
Low Risk
This Affects:
ashTL;DR
When a where guard in an Ash.Reactor change step raises, the step skips the change and reports success, the same as a guard that returns false. Untrusted input that makes the guard raise can skip security-relevant changes such as a privilege downgrade, so the action completes as if it succeeded and leaves the record in an unintended state. The fix fails the step closed when a where guard raises.
Who does this affect?
You are affected if you are using a version that falls within the vulnerable range and you use an Ash.Reactor change step with a where guard on untrusted input.
