The package cached-path-relative before 1.1.0 are vulnerable to Prototype Pollution via the cache variable that is set as {} instead of Object.create(null) in the cachedPathRelative function, which allows access to the parent prototype properties when the object is used to create the cached relative path. When using the origin path as __proto__, the attribute of the object is accessed instead of a path. **Note:** This vulnerability derives from an incomplete fix in https://security.snyk.io/vuln/SNYK-JS-CACHEDPATHRELATIVE-72573

Versions of the package web3-utils before 4.2.1 are vulnerable to Prototype Pollution via the utility functions format and mergeDeep, due to insecure recursive merge. An attacker can manipulate an object's prototype, potentially leading to the alteration of the behavior of all objects inheriting from the affected prototype by passing specially crafted input to these functions.

A vulnerability has been found in Starcounter-Jack JSON-Patch up to 3.1.0 and classified as problematic. This vulnerability affects unknown code. The manipulation leads to improperly controlled modification of object prototype attributes ('prototype pollution'). The attack can be initiated remotely. The exploit has been disclosed to the public and may be used. Upgrading to version 3.1.1 is able to address this issue. The name of the patch is 7ad6af41eabb2d799f698740a91284d762c955c9. It is recommended to upgrade the affected component. VDB-216778 is the identifier assigned to this vulnerability.

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.

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

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.

Prototype pollution vulnerability in the TypeORM package < 0.2.25 may allow attackers to add or modify Object properties leading to further denial of service or SQL injection attacks.

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

Versions of handlebars prior to 4.3.0 are vulnerable to Prototype Pollution leading to Remote Code Execution. Templates may alter an Object's __proto__ and __defineGetter__ properties, which may allow an attacker to execute arbitrary code through crafted payloads.

Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. Prior to versions 5.5.2 and 6.2.1, an attacker can use a prototype pollution sink to trigger a remote code execution through the MongoDB BSON parser. A patch is available in versions 5.5.2 and 6.2.1.

A prototype pollution in the lib.requireFromString function of module-from-string v3.3.1 allows attackers to cause a Denial of Service (DoS) via supplying a crafted payload.

All versions of the package flatnest are vulnerable to Prototype Pollution via the nest() function in the flatnest/nest.js file.

All versions of the package safe-eval are vulnerable to Prototype Pollution via the safeEval function, due to improper sanitization of its parameter content.

Versions of the package underscore-keypath from 0.0.11 are vulnerable to Prototype Pollution via the name argument of the setProperty() function. Exploiting this vulnerability is possible due to improper input sanitization which allows the usage of arguments like “__proto__”.

Versions of the package tough-cookie before 4.1.3 are vulnerable to Prototype Pollution due to improper handling of Cookies when using CookieJar in rejectPublicSuffixes=false mode. This issue arises from the manner in which the objects are initialized.

All versions of the package dot-lens are vulnerable to Prototype Pollution via the set() function in index.js file.
