CVE-2026-82733
Description
Generation of Error Message Containing Sensitive Information vulnerability in ash-project ash_typescript allows an unauthenticated attacker to read internal application data from an HTTP 500 response body. When a typed-controller route handler returns anything other than a %Plug.Conn{}, dispatch/3 in lib/ash_typescript/typed_controller/request_handler.ex passes the value to unexpected_return/2, which interpolates inspect(value, limit: 50) directly into the response message. The limit option bounds elements per collection rather than the term as a whole, so a handler falling through with a term such as {:error, %User{}} or a changeset serialises its full field set, including hashed passwords, tokens, and tenant identifiers, into the JSON error returned to the caller. This contradicts the module's own posture elsewhere: the rescue clause gates Exception.message/1 behind AshTypescript.typed_controller_show_raised_errors?/0 and otherwise returns a generic message, while this path is ungated and always echoes. This issue affects ash_typescript: from 0.15.0 before 0.18.0.
