CVE-2021-23771 2 Argencoders-notevil Project, Notevil Project 2 Argencoders-notevil, Notevil 2026-06-17 6.4 MEDIUM 6.5 MEDIUM
This affects all versions of package notevil; all versions of package argencoders-notevil. It is vulnerable to Sandbox Escape leading to Prototype pollution. The package fails to restrict access to the main context, allowing an attacker to add or modify an object's prototype. **Note:** This vulnerability derives from an incomplete fix in [SNYK-JS-NOTEVIL-608878](https://security.snyk.io/vuln/SNYK-JS-NOTEVIL-608878).
CVE-2021-23760 1 Keyget Project 1 Keyget 2026-06-17 7.5 HIGH 5.6 MEDIUM
The package keyget from 0.0.0 are vulnerable to Prototype Pollution via the methods set, push, and at which could allow an attacker to cause a denial of service and may lead to remote code execution. **Note:** This vulnerability derives from an incomplete fix to [CVE-2020-28272](https://security.snyk.io/vuln/SNYK-JS-KEYGET-1048048)
CVE-2021-23702 1 Object-extend Project 1 Object-extend 2026-06-17 7.5 HIGH 7.6 HIGH
The package object-extend from 0.0.0 are vulnerable to Prototype Pollution via object-extend.
CVE-2021-23700 1 Merge-deep2 Project 1 Merge-deep2 2026-06-17 7.5 HIGH 6.5 MEDIUM
All versions of package merge-deep2 are vulnerable to Prototype Pollution via the mergeDeep() function.
CVE-2021-23682 2 Appwrite, Litespeed.js Project 2 Appwrite, Litespeed.js 2026-06-17 7.5 HIGH 7.3 HIGH
This affects the package litespeed.js before 0.3.12; the package appwrite/server-ce from 0.12.0 and before 0.12.2, before 0.11.1. When parsing the query string in the getJsonFromUrl function, the key that is set in the result object is not properly sanitized leading to a Prototype Pollution vulnerability.
CVE-2021-23663 1 Sey Project 1 Sey 2026-06-17 7.5 HIGH 6.5 MEDIUM
All versions of package sey are vulnerable to Prototype Pollution via the deepmerge() function.
