Kobako:Handle 機制,沙盒裡的 mruby 不認識 User,User.find_by 的回傳值要怎麼交回去?蒼時借用指標的概念,只傳編號不傳物件,無法序列化的物件包成 Kobako::Handle,Host 再用編號查表取回,ActiveRecord 的方法鏈也能串起來,只是越好用的機制,權限邊界也越難掌握

Ruby 生態系缺少適合執行 AI 生成程式碼的環境,蒼時選了 WebAssembly 搭配 mruby 做出 Kobako,沙盒內外的呼叫借鑑 dRuby 的 method_missing,目標是輕量又容易使用,其他方案不是不行,只是不符合這兩個條件

Kobako 沙盒語言選了 mruby,序列化格式就得重新取捨。Marshal 在 mruby 沒有對應機制,JSON 空間大又慢,Protobuf 要預先編譯 Schema,蒼時最後選了 MessagePack,[type][len][data] 的結構更緊湊,Fluent Bit 跟 mruby-engine 也驗證過可行

「AI 時代為什麼還用 Ruby」,蒼時在 COSCUP 2026 後的答案先是喜歡,再補上實驗、開放標準(mruby、MessagePack、Wasmtime 與 WasmEdge)與開源的意義。結論是 Kobako「不限於 Ruby」的設計理念優先於語言本身

CVE-2026-55107 - Kobako Vulnerable to Sandbox Escape: guest eval reaches host RCE via method_missing → public_send (any bound Service)
Kobako is a Ruby gem that embeds a Wasm-isolated mruby interpreter inside applications, allowing execution of untrusted Ruby scripts (LLM-generated code, user formulas, student submissions, third-party plugins) in-process without giving them access to host memory, files, network, or credentials. From version 0.1.0 to before version 0.9.1, a guest mruby script …

Beni 這次把例外處理整個翻新了一輪,更新到達 v0.16,原本呼叫 intern 或定義全域常數這類操作,如果 mruby 內部丟出例外,例外會直接跨過 Rust 的堆疊往上長跳,遇到中間的保護框架就屬於未定義行為,現在這些操作改成回傳 Result,呼叫方能用 match 或 ? 接住例外,同時把舊的 protect、rescue、ensure 整組機制拿掉,改用新的保護原語

這次也有幾個不相容的變更,之前有使用請小心

Kobako:標準輸出,討論 mruby 在 WebAssembly 裡怎麼做出看得到的輸出。mruby-io 這個 Gem 照 POSIX 慣例寫成,但 WASI Preview 1 不符合,編譯會失敗。蒼時改用 Wasmtime 的 MemoryOutputPipe 把 stdout 接到記憶體,不再依賴檔案系統

預期能讓 AI 沙盒更安全,同時保留輸出能力

mruby 🤝 Ruby

In my ongoing exploration of non-deterministic agents running along side deterministic code, I figured I'd see if I could use RubyLLM to run arbitrary ruby code inside of an mruby sandbox within the same process.

It works!

There's obviously more to it than 41 lines of bash, but that's because I realized ruby-install, ruby-build, etc. are doing the hard work of making Ruby builds easy.

I'm standing on the shoulders of the giants that compile Ruby into a folder, then I set various paths and it works.
