CVE-2026-34593 is a high-severity flaw (CVSS 7.5) affecting ash framework. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

Ash Framework is a declarative, extensible framework for building Elixir applications. Prior to version 3.22.0, Ash.Type.Module.cast_input/2 unconditionally creates a new Erlang atom via Module.concat([value]) for any user-supplied binary string that starts with "Elixir.", before verifying whether the referenced module exists. Because Erlang atoms are never garbage-collected and the BEAM atom table has a hard default limit of approximately 1,048,
