Dynamoose is an open-source modeling tool for Amazon's DynamoDB. In Dynamoose from version 2.0.0 and before version 2.7.0 there was a prototype pollution vulnerability in the internal utility method "lib/utils/object/set.ts". This method is used throughout the codebase for various operations throughout Dynamoose. We have not seen any evidence of this vulnerability being exploited. There is no evidence this vulnerability impacts versions 1.x.x since the vulnerable method was added as part of the v2 rewrite. This vulnerability also impacts v2.x.x beta/alpha versions. Version 2.7.0 includes a patch for this vulnerability.

Prototype pollution vulnerability in MrSwitch hello.js version 1.18.6, allows remote attackers to execute arbitrary code via hello.utils.extend function.

Underscore.deep is a collection of Underscore mixins that operate on nested objects. Versions of `underscore.deep` prior to version 0.5.3 are vulnerable to a prototype pollution vulnerability. An attacker can craft a malicious payload and pass it to `deepFromFlat`, which would pollute any future Objects created. Any users that have `deepFromFlat` or `deepPick` (due to its dependency on `deepFromFlat`) in their code should upgrade to version 0.5.3 as soon as possible. Users unable to upgrade may mitigate this issue by modifying `deepFromFlat` to prevent specific keywords which will prevent this from happening.

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)

This affects all versions of package json-ptr. The issue occurs in the set operation (https://flitbit.github.io/json-ptr/classes/_src_pointer_.jsonpointer.htmlset) when the force flag is set to true. The function recursively set the property in the target object, however it does not properly check the key being set, leading to a prototype pollution.

confinit through 0.3.0 is vulnerable to Prototype Pollution.The 'setDeepProperty' function could be tricked into adding or modifying properties of 'Object.prototype' using a '__proto__' payload.

ini-parser through 0.0.2 is vulnerable to Prototype Pollution.The library could be tricked into adding or modifying properties of Object.prototype using a '__proto__' payload.

This affects the package json8 before 1.0.3. The function adds in the target object the property specified in the path, however it does not properly check the key being set, leading to a 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)

In all versions of package casperjs, the mergeObjects utility function is susceptible to Prototype Pollution.

Prototype pollution vulnerability in dot-prop npm package versions before 4.2.1 and versions 5.x before 5.1.1 allows an attacker to add arbitrary properties to JavaScript language constructs such as objects.

All versions of package safe-eval are vulnerable to Prototype Pollution which allows an attacker to add or modify properties of the Object.prototype.Consolidate when using the function safeEval. This is because the function uses vm variable, leading an attacker to modify properties of the Object.prototype.

All versions of package safe-object2 are vulnerable to Prototype Pollution via the setter function.

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

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)

All versions of package worksmith are vulnerable to Prototype Pollution via the setValue function.

querymen prior to 2.1.4 allows modification of object properties. The parameters of exported function handler(type, name, fn) can be controlled by users without any sanitization. This could be abused for Prototype Pollution attacks.

All versions of package gammautils are vulnerable to Prototype Pollution via the deepSet and deepMerge functions.

All versions of package node-oojs are vulnerable to Prototype Pollution via the setPath function.

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)

The package linux-cmdline before 1.0.1 are vulnerable to Prototype Pollution via the constructor.

The package asciitable.js before 1.0.3 are vulnerable to Prototype Pollution via the main function.

deepmerge-ts is a typescript library providing functionality to deep merging of javascript objects. deepmerge-ts is vulnerable to Prototype Pollution via file deepmerge.ts, function defaultMergeRecords(). This issue has been patched in version 4.0.2. There are no known workarounds for this issue.

sds through 3.2.0 is vulnerable to Prototype Pollution.The library could be tricked into adding or modifying properties of the 'Object.prototype' by abusing the 'set' function located in 'js/set.js'.

express-mock-middleware through 0.0.6 is vulnerable to Prototype Pollution. Exported functions by the package can be tricked into adding or modifying properties of the `Object.prototype`. Exploitation of this vulnerability requires creation of a new directory where an attack code can be placed which will then be exported by `express-mock-middleware`. As such, this is considered to be a low risk.

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.
