wasm-binary-security

The exploit is against a vulnerable library (the actual input file is here: https://github.com/sola-st/wasm-binary-security/blob/master/...) If you have a wasm application with vulnerabilities (e.g. in the libraries) there are no mitigations that native binaries provide, so simple buffer overflows give you RCEs again. It's still within the sandbox, but the threat is as severe as running eval on user supplied inputs as there might be useful stuff in that sandbox.
