These values are passed to 'Elixir.PhoenixStorybook.Helpers.ExtraAssignsHelpers':handle_set_variation_assign/3, which stores them verbatim. When rendering, 'Elixir.PhoenixStorybook.Rendering.ComponentRenderer':attributes_markup/1 interpolates binary attribute values directly into a HEEx template string as name=\"<val>\" without escaping double quotes or HEEx expression delimiters. An attacker can supply a value containing a closing quote followed by a HEEx expression block (e.g. foo\" injected={EXPR} bar=\"), which causes EXPR to be treated as an inline Elixir expression. The resulting template is compiled via EEx.compile_string/2 and executed via Code.eval_quoted_with_env/3 with full Kernel imports and no sandbox, giving the attacker arbitrary code execution on the server.\n\nThis issue affects phoenix_storybook from 0.5.0 before 1.1.0."},{"lang":"es","value":"Vulnerabilidad de inyección de código en phenixdigital phoenix_storybook permite la ejecución remota de código no autenticada a través de la interpolación de valores de atributos no saneados en la generación de plantillas HEEx.\n\nEl gestor de eventos WebSocket psb-assign en 'Elixir.PhoenixStorybook.Story.PlaygroundPreviewLive':handle_event/3 acepta nombres y valores de atributos arbitrarios de clientes no autenticados.
