CWE-1321

All versions of package gedi are vulnerable to Prototype Pollution via the set function.

The package bmoor before 0.8.12 are vulnerable to Prototype Pollution via the set function.

All versions of package safetydance are vulnerable to Prototype Pollution via the set function.

The package mathjs before 7.5.1 are vulnerable to Prototype Pollution via the deepExtend function that runs upon configuration updates.

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.

This affects the package @tsed/core before 5.65.7. This vulnerability relates to the deepExtend function which is used as part of the utils directory. Depending on if user input is provided, an attacker can overwrite and pollute the object prototype of a program.
