Title: ash de ash-project, Description: Ash Framework es un framework declarativo y extensible para construir aplicaciones Elixir. Antes de la versión 3.22.0, Ash.Type.Module.cast_input/2 crea incondicionalmente un nuevo átomo de Erlang a través de Module.concat([value]) para cualquier cadena binaria proporcionada por el usuario que comienza con 'Elixir.', antes de verificar si el módulo referenciado existe. Debido a que los átomos de Erlang nunca son recolectados por el recolector de basura y la tabla de átomos de BEAM tiene un límite predeterminado estricto de aproximadamente 1.048.576 entradas, un atacante que puede enviar valores a cualquier atributo de recurso o argumento de tipo :module puede agotar esta tabla y colapsar toda la VM de BEAM, derribando la aplicación. Este problema ha sido parcheado en la versión 3.22.0.

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.
