From aaf2cfa7612bb858764994c9f250e440b5d8d970 Mon Sep 17 00:00:00 2001 From: fylorn <249551762+fylorn@users.noreply.github.com> Date: Fri, 2 Oct 2026 19:49:41 +0800 Subject: [PATCH 1/3] Plugin security tests: adversarial corpus, sandbox and end-to-end tests, example plugins An adversarial corpus in crates/tw-plugin/tests/corpus/, one small plugin per attack: CPU and memory exhaustion, stack overflow inside the engine, outputs that are huge, cyclic, deeply nested or hidden behind getters, Proxies and toJSON, odd throws, log floods, held-back replies, probes for globals, modules, I/O and state, ctx and built-in tampering, and edits that break the view's rules. Runtime tests run the corpus against tw-plugin: every attack fails as a RunError or LoadError within bounded time, fails the same way a second time, and leaves the runtime working. They also pin the global object to the ECMAScript built-ins plus console and reject, the sandbox's imports to the log and the clock, fresh state per request and per reply, the SHA-256 of the loaded bytes, and that no core crate builds a JavaScript engine natively. The gateway tests send real requests through real plugins in the real sandbox to fake upstreams: placeholders instead of keys in request, reply and tool-call hooks in every redaction mode, only the granted sections, redaction, content screening, hidden characters, the tool-call guard and the output limit applied to plugin output, the key's model list applied to a model a plugin chose, one request-hook run across failover and the unsealed resend, a changed file not run under reject and skip, rule-breaking edits refused, no state across requests or replies, and every run recorded. A property test checks that each kind of breach is refused in all four formats. The harness wires tw-plugin behind the Engine seam itself until the production adapter lands. Two tests are ignored with the reason: a reply plugin can write <> into a tool call and the gateway reveals the real key there, and token-count requests reach the upstream without the request hooks' rewrite. Five example plugins in examples/plugins/ (date in the system prompt, term unification in stream mode, stripping a parameter, masking a pattern, WSL and Windows paths in tool calls) are loaded and run on fixtures, and four of them also through the gateway.

Those tests now run on a runtime whose CPU budget is in seconds, so the limit they target is the one they hit; the CPU limits keep their own tests on the default runtime. The reply hooks that test the CPU budgets burned time by watching the clock. A descheduled thread lets the clock run while using no CPU, so under load a 60 ms busy-wait could finish inside a 20 ms CPU budget. The per-call case is now an endless loop, and the per-reply case does a fixed amount of work per call against a runtime with a 2 s per-call and a 300 ms per-reply budget. The dependency check read the full graph with `cargo metadata --offline`, which needs every platform's packages and failed on the macOS runner. It now reads the workspace's Cargo.lock, which also covers build and dev dependencies, and uses `--no-deps` for the member checks.

New end-to-end tests: - A request that no plugin changes reaches the upstream byte for byte, with odd whitespace, `1.0`, an integer beyond double precision, `1e3` and an escaped character, whether the plugin hands the view back or returns nothing. - On the Responses WebSocket, the request hook on `response.create` and the reply hook on the event stream see placeholders and the client still gets its key back, a dangerous call written by a plugin is cut, and a refusal never reaches the upstream. Rule-breaking edits now also check the recorded message code and the client's error, and the output-limit test checks that the cut came from the plugin's text.
