Bump wasmtime to 49.0.3 and rustls to 0.23.46 (RustSec advisories) - #339

Conversation
The scheduled Audit on main fails on RUSTSEC-2026-0353 to -0364 (wasmtime 49.0.2) and RUSTSEC-2026-0346 to -0349 (rustls 0.23.45). tw-plugin pins Wasmtime exactly in both [dependencies] and [build-dependencies]: the sandbox is precompiled in build.rs and only loads in the same release, so both pins move to 49.0.3 together. Cranelift and the wasmtime-internal crates follow; wasmparser and wasm-encoder stay at 0.258.3. rustls moves with cargo update -p rustls. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

tw-pluginpins the exact version in both[dependencies]and[build-dependencies], because the sandbox's machine code is precompiled inbuild.rsand only loads in the same Wasmtime release; both pins move together. Cranelift and thewasmtime-internal-*crates follow to 0.136.3 / 49.0.3;wasmparserandwasm-encoderstay at 0.258.3.cargo update -p rustls.Only

Low for both. Most of the Wasmtime advisories are in the component model, which the plugin sandbox does not enable (core modules only,
runtime+std). The rustls build here has no brotli certificate decompression and the gateway does not configure ECH; the remaining two (sessionDebugoutput, a key-exchange downgrade on later connections) are fixed by the bump.Verification
cargo test -p tw-pluginpasses:build.rsprecompiles the sandbox with Cranelift 0.136.3 and the tests load and run it under the 49.0.3 runtime.Cargo.lockchanged.🤖 Generated with Claude Code
