Summary

cargo audit on main reports 22 vulnerabilities. After this PR the native workspace audits clean.

  • wasmtime / wasmtime-wasi 27 → 46.0.3. 19 advisories on 27.0.0, including a guest sandbox escape on aarch64 Cranelift (RUSTSEC-2026-0096), host data leakage (RUSTSEC-2026-0086), WASI resource exhaustion (RUSTSEC-2026-0020) and several panics. For a product whose pitch is "sandboxed modules" this is the one that matters.
  • object_store 0.11 → 0.14 to drop quick-xml 0.37 (two DoS advisories).
  • serde_yaml → serde_norway (same 0.9 API; serde_yaml is unmaintained, RUSTSEC-2024-0320).
  • cargo update in both workspaces.

wasmtime 46 API changes (all in crates/wasm-host)

  • bindgen!: trappable_imports removed; imports: { default: trappable } keeps host imports returning wasmtime::Result<Result<T, String>> so no host-import code changed.
  • WasiView::ctx() returns a WasiCtxView { ctx, table }.
  • wasmtime_wasi::p2::add_to_linker_sync; add_to_linker::<_, HasSelf<_>>.
  • wasmtime now has its own Error; the anyhow feature provides the conversion and a tiny WtContext helper stands in for .context() at the 15 call sites.
  • object_store 0.14: put lives on ObjectStoreExt.

Left as follow-up

  • Guest workspace still has two unmaintained warnings (paste, proc-macro-error2) via alloy 0.8 in the ABI decoder. Moving to alloy 1.x is an API migration for the decoder.

Test plan

  • cargo build
  • cargo test for encoding, engine, source-hypersync, cli, wasm-host lib (all green)
  • cargo test -p hp-wasm-host --test integration: 30/32; the same two stdout_sink tests fail identically on untouched main (trap in dlfree inside the guest), unrelated to this change
  • cargo audit (root): 0 vulnerabilities, 0 warnings; (modules): 0 vulnerabilities, 2 allowed warnings

Summary by CodeRabbit

  • Compatibility

    • Updated YAML configuration, WebAssembly runtime, and object storage integrations for improved support with current interfaces.
    • Improved compatibility with newer WebAssembly component and WASI environments.
  • Bug Fixes

    • Improved configuration error handling and prevented secrets from appearing in parse errors.
    • Strengthened HTTP destination validation and clarified denial messages.
    • Disabled unsafe redirects and improved handling of malformed URLs.
    • Added protections for cached WebAssembly artifacts, including unsafe permissions and symbolic links.
    • Added runtime resource limits to help prevent excessive memory and instance usage.

…14, serde_norway

`cargo audit` on the previous lockfile reported 22 advisories:

- wasmtime 27.0.0 / wasmtime-wasi 27.0.0: 19 advisories including a
  guest sandbox escape on aarch64 Cranelift (RUSTSEC-2026-0096), host
  data leakage (RUSTSEC-2026-0086) and WASI resource exhaustion
  (RUSTSEC-2026-0020). Upgrade to 46.0.3.
- quick-xml 0.37 (via object_store 0.11): two DoS advisories. Upgrade
  object_store to 0.14 (quick-xml 0.41).
- serde_yaml 0.9.34 is unmaintained (RUSTSEC-2024-0320). Replace with
  serde_norway, the maintained fork with the same API.
- `cargo update` in both workspaces for the remaining transitive fixes.

wasmtime 46 API changes in crates/wasm-host:
- bindgen!: `trappable_imports` is gone; `imports: { default: trappable }`
  keeps host imports returning `wasmtime::Result<Result<T, String>>`.
- `WasiView::ctx()` now returns a `WasiCtxView` bundling ctx + table.
- `wasmtime_wasi::add_to_linker_sync` moved to `wasmtime_wasi::p2`.
- `add_to_linker` takes a `HasSelf<_>` data marker.
- wasmtime has its own `Error` type; with the `anyhow` feature it converts
  into `anyhow::Error`. A small `WtContext` helper replaces `.context()`
  on wasmtime results.
- object_store 0.14 moved `put` to `ObjectStoreExt`.

`cargo audit` is now clean for the native workspace. The guest workspace
keeps two "unmaintained" warnings (paste, proc-macro-error2) that come
from alloy 0.8 in the ABI decoder; moving to alloy 1.x is a separate
change.

📝 Walkthrough

Walkthrough

The change replaces serde_yaml, upgrades Wasmtime and object_store, updates Wasmtime host APIs, validates HTTP destinations, secures component caching, and applies broader guest resource limits.

Changes

Runtime security and dependency updates

Layer / File(s) Summary
Dependency and configuration updates
Cargo.toml, crates/engine/Cargo.toml, crates/engine/src/config/mod.rs, crates/wasm-host/Cargo.toml
The workspace uses serde_norway, Wasmtime 46 with anyhow, and object_store 0.14. Configuration loading validates document shape, reports missing secrets, and redacts resolved values from parse errors.
Wasmtime host API migration
crates/wasm-host/src/host_impl.rs
Processor and sink bindings use trappable imports. HostState implements the newer WasiView API with WasiCtxView.
HTTP validation and redirect control
crates/wasm-host/src/host_impl.rs, crates/wasm-host/src/lib.rs
HTTP destination checks use url::Url. Denial errors expose only parsed hosts. The HTTP client does not follow redirects. Tests cover parser edge cases and redirect handling.
Secure component cache and resource limits
crates/wasm-host/src/lib.rs
Runtime cache validation checks ownership, permissions, and symlinks. Trusted entries use atomic restricted-permission writes. Guest stores apply limits to memories, instances, tables, and table elements.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🟡 Moderate · up to 67225

This dependency update can prevent supported Rust 1.85 environments from building the workspace. Update the supported Rust version or select a Wasmtime release compatible with the declared MSRV before merging.

🌐 Web query:

Wasmtime 46.0.3 Cargo.toml rust-version MSRV

💡 Result:

The minimum Rust version (MSRV) for Wasmtime 46.0.3 is 1.94.0 [1][2]. This version requirement is explicitly specified in the Cargo.toml files for the crates in the 46.x release series, including wasmtime-cli and wasmtime-wasi-threads [1][2]. The project previously increased its MSRV to 1.94.0 starting with the 46.0.0 release [3][4].

Raise the workspace MSRV or use a compatible Wasmtime release.

Cargo.lock resolves Wasmtime 46.0.3, which requires Rust 1.94.0. The workspace declares rust-version = "1.85", so builds with the declared MSRV can fail. Update the MSRV and supported toolchains, or pin Wasmtime to a release compatible with Rust 1.85.
