Background
The bmoor package is an npm package that provides various utility functions for JavaScript applications. It is widely used in many projects and offers features such as data manipulation, validation, and more. However, versions prior to 0.10.1 are vulnerable to Prototype Pollution due to missing sanitization in the set function.
Vulnerability Detail
Prototype Pollution is a vulnerability that allows an attacker to modify the prototype of an object, leading to unexpected behavior in the application. In the case of bmoor, the set function does not properly sanitize user input, allowing an attacker to inject malicious properties into the prototype chain. This can lead to various security issues, including remote code execution, data manipulation, and privilege escalation.
How To Fix
Minimum fixed version
0.10.1
This is the first release that contains the fix.

Workaround
If upgrading to the latest version is not immediately feasible, developers can mitigate the risk by implementing input validation and sanitization in their application code. This involves carefully validating and filtering user input before passing it to the vulnerable functions in bmoor. By ensuring that only safe and expected values are processed, the risk of Prototype Pollution can be significantly reduced.
Conclusion
The bmoor package prior to version 0.10.1 is vulnerable to Prototype Pollution, which can lead to serious security issues. It is crucial for developers to upgrade to the latest version or apply input validation and sanitization to mitigate the risk.
