CVE-2026-119139Wasmtime 46.0.0 before 48.0.6 and 49.0.0 before 49.0.3 Host Panic via Func::call

Beschreibung

Wasmtime 46.0.0 before 48.0.6 and 49.0.0 before 49.0.3 contains a leftover assertion in component::Func::call that rejects guest exports using the async ABI option. An attacker who supplies a component with an async-lifted export can crash the host process when an embedder invokes that export through Func::call.
