Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (4.74%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
This affects the package chart.js before 2.9.4. The options parameter is not properly sanitized when it is processed. When the options are processed, the existing options (or the defaults options) are deeply merged with provided options. However, during this operation, the keys of the object being set are not checked, leading to a prototype pollution.
