CVE-2026-82744: Not Failing Securely

Not Failing Securely Failing Open vulnerability in ash-project ash skips an Ash.Reactor change when the guard controlling it raises, so a change meant to run does not. An Ash.Reactor change step can be gated by where validations that decide whether the change runs. Ash.Reactor.ChangeStep...

Improper Validation of Specified Type of Input vulnerability in ash-project ash lets an attacker confuse the stored type tag of an Ash.Type.Union value that uses storage: :map with tag, bypassing that member's validation and any tag-based authorization. For a union with storage: :map with tag, ea...
