• crates.io js-sandbox: <= 0.1.6 (no fix yet)
Description
Affected versions use deno_core releases that expose `Deno.core.ops.op_panic` to the JS runtime in the base core
This function when called triggers a manual panic in the thread containing the runtime, breaking sandboxing
It can be fixed by stubbing out the exposed op:
```javascript
Deno.core.ops.op_panic = (msg) => { throw new Error(msg) };
```
