## Impact Users running Vega/Vega-lite JSON definitions could run unexpected JavaScript code when drawing graphs, unless the library is used with the `vega-interpreter`. ## Workarounds - Use `vega` with [expression interpreter](https://vega.github.io/vega/usage/interpreter/) - Upgrade to a [newer Vega version](https://github.com/vega/vega/releases/tag/v5.32.0) (`5.32.0`) ### POC Summary Calling `replace` with a `RegExp`-like pattern calls `RegExp.prototype[@@replace]`, which can then call an attacker-controlled `exec` function. ### POC Details Consider the function call `replace('foo', {__proto__: /h/.constructor.prototype, global: false})`. Since `pattern` has `RegExp.prototype[@@replace]`, `pattern.exec('foo')` winds up being called. The resulting malicious call looks like this: ``` replace(<string argument>, {__proto__: /h/.constructor.prototype, exec: <function>, global: false}) ``` Since functions cannot be returned from this, an attacker that wishes to escalate to XSS mu...

Server-Side Request Forgery (SSRF) vulnerability in Apache Kylin. Through a kylin server, an attacker may forge a request to invoke "/kylin/api/xxx/diag" api on another internal host and possibly get leaked information.
