Wasmtime 46.0.0 before 48.0.6 and 49.0.0 before 49.0.3 contains a denial of service vulnerability where dropping the Future returned by TypedFunc::callasync can panic the host. When the guest task has not started, cleanup code searches only one location for work items and unwraps the resulting...

CVE-2026-119137

The Wasmtime runtime is vulnerable to a stack overflow in versions 42.0.0 before 48.0.6 and 49.0.0 before 49.0.3 . The root cause is uncontrolled recursion (CWE-674) occurring during recursive type drops. A guest can define a long chain of recursive types; removing the top-level type triggers unb...
