    Published: 22 Dec 2023Last Modified: 12 Aug 2026

    Summary: Filesystem sandbox not enforced in wasmer-cli

    Details: Wasmer is a WebAssembly runtime that enables containers to run anywhere: from Desktop to the Cloud, Edge and even the browser. Wasm programs can access the filesystem outside of the sandbox. Service providers running untrusted Wasm code on Wasmer can unexpectedly expose the host filesystem. This vulnerability has been patched in version 4.2.4.
