Medium (5.5) in bytecodealliance wasmtime. EPSS 0.3% chance of exploitation in the next 30 days. Fixed in wasmtime 19.0.1.
wasmtime is a runtime for WebAssembly. The 19.0.0 release of Wasmtime contains a regression introduced during its development which can lead to a guest WebAssembly module causing a panic in the host runtime. A valid WebAssembly module, when executed at runtime, may cause this panic. This vulnerability has been patched in version 19.0.1.
