Vulnerability Title
Ash Framework: Ash.Type.Module.cast_input/2 atom exhaustion via unchecked Module.concat allows BEAM VM crash
Vulnerability Description
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 1,048,576 entries, an attacker who can submit values to any resource attribute or argument of type :module can exhaust this table and crash the entire BEAM VM, taking down the application. This issue has been patched in version 3.22.0.

Vulnerability Title
Ash Framework 资源管理错误漏洞
Vulnerability Description
Ash Framework是Ash Framework开源的一个用于构建Elixir应用程序的框架。 Ash Framework 3.22.0之前版本存在资源管理错误漏洞，该漏洞源于Ash.Type.Module.cast_input/2无条件地为任何以 Elixir. 开头的用户提供二进制字符串创建新的Erlang原子，可能导致耗尽原子表并使整个BEAM虚拟机崩溃。
