Background
Djv is an npm package that provides a lightweight and efficient JSON schema validator. It is commonly used in JavaScript applications to validate and enforce data structures based on predefined schemas. Djv allows developers to define and validate JSON schemas, ensuring data consistency and integrity. However, versions of djv prior to 2.1.4 are vulnerable to arbitrary code execution. This means that an attacker can manipulate the schema file to inject and execute arbitrary JavaScript code on the victim's machine, potentially leading to unauthorized access, data breaches, or other malicious activities.
Vulnerability Detail
The vulnerability (CVE-2020-28464) in djv arises from a lack of proper input validation and sanitization when processing the schema file. By crafting a malicious schema file, an attacker can exploit this weakness and execute arbitrary JavaScript code on the target system. This code execution can have severe consequences, including unauthorized access to sensitive information, remote code execution, or the installation of malware. The vulnerability has a CVSS score of 9.8, indicating its critical severity.
How To Fix

Workaround
As a temporary workaround, developers can implement strict input validation and sanitization when processing the schema file. By thoroughly validating and sanitizing the schema input, the risk of code injection can be reduced. However, this workaround is not recommended as it may not provide complete protection against all possible attack vectors. It is strongly advised to update to the latest version of djv as soon as possible.
Conclusion
The vulnerability (CVE-2020-28464) in djv exposes applications to arbitrary code execution, allowing attackers to run malicious JavaScript code on the victim's machine. To mitigate this risk, it is crucial to update the djv package to version 2.1.4 or later. This update includes the necessary security patches to prevent code injection and protect against potential unauthorized access or data breaches.
