Prototype Pollution in the merge and clone helper methods
Impact
Using merge and clone helper methods in the src/core/util.ts module will have prototype pollution. It will affect the popular data visualization library Apache ECharts, which is using and exported these two methods directly.
Patches
It has been patched in https://github.com/ecomfe/zrender/pull/826.
Users should update zrender to 5.2.1. and update echarts to 5.2.1 if project is using echarts.

ZRender is a lightweight graphic library providing 2d draw for Apache ECharts. In versions prior to 5.2.1, using `merge` and `clone` helper methods in the `src/core/util.ts` module results in prototype pollution. It affects the popular data visualization library Apache ECharts, which uses and exports these two methods directly. The GitHub Security Advisory page for this vulnerability contains a proof of concept. This issue is patched in ZRender version 5.2.1. One workaround is available: Check if there is `__proto__` in the object keys. Omit it before using it as an parameter in these affected methods. Or in `echarts.util.merge` and `setOption` if project is using ECharts.
