A prototype pollution vulnerability exists in the function copy in dom.js in the xmldom (published as @xmldom/xmldom) package before 0.8.3 for Node.js via the p variable. NOTE: the vendor states "we are in the process of marking this report as invalid"; however, some third parties takes the position that "A prototype injection/Prototype pollution is not just when global objects are polluted with recursive merge or deep cloning but also when a target object is polluted."

Prototype pollution vulnerability in beautify-web js-beautify 1.13.7 via the name variable in options.js.

loader-utils: prototype pollution in function parseQuery in parseQuery.js

Prototype pollution vulnerability in function parseQuery in parseQuery.js in webpack loader-utils via the name variable in parseQuery.js. This affects all versions prior to 1.4.1 and 2.0.3.

uglify-js: Prototype pollution vulnerability in function DEFNODE in ast.js

Prototype pollution vulnerability in function DEFNODE in ast.js in mishoo UglifyJS 3.13.2 via the name variable in ast.js. NOTE: the vendor considers this an invalid report.

Prototype pollution vulnerability in function extend in babel.js in stealjs steal 2.2.4 via the key variable in babel.js.

Prototype pollution vulnerability in stealjs steal 2.2.4 via the optionName variable in main.js.

Prototype pollution vulnerability in function convertLater in npm-convert.js in stealjs steal 2.2.4 via the packageName variable in npm-convert.js.

Prototype pollution vulnerability in function convertLater in npm-convert.js in stealjs steal 2.2.4 via the requestedVersion variable in npm-convert.js.

Prototype Pollution in automattic/mongoose

Prototype Pollution in GitHub repository automattic/mongoose prior to 6.4.6.

Simple-Plist v1.3.0 was discovered to contain a prototype pollution vulnerability via .parse().

Prototype Pollution

The package ts-deepmerge before 2.0.2 are vulnerable to Prototype Pollution due to missing sanitization of the merge function.

Prototype Pollution

The package protobufjs before 6.11.3 are vulnerable to Prototype Pollution which can allow an attacker to add/modify properties of the Object.prototype. This vulnerability can occur in multiple ways: 1. by providing untrusted user input to util.setProperty or to ReflectionObject.setParsedOption functions 2. by parsing/loading .proto files

Prototype Pollution

All versions of package querymen are vulnerable to Prototype Pollution if the parameters of exported function handler(type, name, fn) can be controlled by users without any sanitization. Note: This vulnerability derives from an incomplete fix of [CVE-2020-7600](https://security.snyk.io/vuln/SNYK-JS-QUERYMEN-559867).

Prototype Pollution

This affects the package sds from 0.0.0. The library could be tricked into adding or modifying properties of the Object.prototype by abusing the set function located in js/set.js. **Note:** This vulnerability derives from an incomplete fix to [CVE-2020-7618](https://security.snyk.io/vuln/SNYK-JS-SDS-564123)

Prototype Pollution

All versions of package dset are vulnerable to Prototype Pollution via 'dset/merge' mode, as the dset function checks for prototype pollution by validating if the top-level path contains __proto__, constructor or protorype. By crafting a malicious object, it is possible to bypass this check and achieve prototype pollution.

Prototype Pollution

The package set-in before 2.0.3 are vulnerable to Prototype Pollution via the setIn method, as it allows an attacker to merge object prototypes into it. **Note:** This vulnerability derives from an incomplete fix of [CVE-2020-28273](https://security.snyk.io/vuln/SNYK-JS-SETIN-1048049)

Prototype Pollution

The package libnested before 1.5.2 are vulnerable to Prototype Pollution via the set function in index.js. **Note:** This vulnerability derives from an incomplete fix for [CVE-2020-28283](https://security.snyk.io/vuln/SNYK-JS-LIBNESTED-1054930)

Denial of Service (DoS)

All versions of package bignum are vulnerable to Denial of Service (DoS) due to a type-check exception in V8, when verifying the type of the second argument to the .powm function, V8 will crash regardless of Node try/catch blocks.

Prototype Pollution

All versions of package jsgui-lang-essentials are vulnerable to Prototype Pollution due to allowing all Object attributes to be altered, including their magical attributes such as proto, constructor and prototype.

Prototype Pollution

The package bodymen from 0.0.0 are vulnerable to Prototype Pollution via the handler function which could be tricked into adding or modifying properties of Object.prototype using a __proto__ payload. **Note:** This vulnerability derives from an incomplete fix to [CVE-2019-10792](https://security.snyk.io/vuln/SNYK-JS-BODYMEN-548897)
