I'm not a rust expert, but I thought rust without unsafes should prevent such things at the compile time. C# and Java will be compiled into WASM differently, I believe no less securely than JVM or .NET. Having information leaks is still better than arbitrary code execution.

No safe language in the world prevents anything if the attacker can change the binary contents, it is no longer the code produced by the compiler.

That is why we have signed binary execution to start with, WASM doesn't support any of this.
