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.

Prototype pollution vulnerability in tschaub gh-pages 3.1.0 via the partial variable in util.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.

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

almela obx before v.0.0.4 has a Prototype Pollution issue which allows arbitrary code execution via the obx/build/index.js:656), reduce (@almela/obx/build/index.js:470), Object.set (obx/build/index.js:269) component.

Prototype pollution vulnerability in stealjs steal 2.2.4 via the alias variable in babel.js.

A prototype pollution in the function fieldsToJson of node-opcua-alarm-condition v2.134.0 allows attackers to cause a Denial of Service (DoS) via supplying a crafted payload.

A prototype pollution in the lib.createPath function of utile v0.3.0 allows attackers to cause a Denial of Service (DoS) via supplying a crafted payload.

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

A prototype pollution in the lib.parse function of dot-qs v0.2.0 allows attackers to cause a Denial of Service (DoS) via supplying a crafted payload.

Prototype pollution vulnerability in 'js-extend' versions 0.0.1 through 1.0.1 allows attacker to cause a denial of service and may lead to remote code execution.

Prototype pollution vulnerability in 'safe-flat' versions 2.0.0 through 2.0.1 allows an attacker to cause a denial of service and may lead to remote code execution.

This affects all versions of package mout. The deepFillIn function can be used to 'fill missing properties recursively', while the deepMixIn 'mixes objects into the target object, recursively mixing existing child objects as well'. In both cases, the key used to access the target object recursively is not checked, leading to a Prototype Pollution.

This affects the package ini before 1.3.6. If an attacker submits a malicious INI file to an application that parses it with ini.parse, they will pollute the prototype on the application. This can be exploited further depending on the context.

This affects the package express-fileupload before 1.1.8. If the parseNested option is enabled, sending a corrupt HTTP request can lead to denial of service or arbitrary code execution.
