Node.js Code Injection Binary Parser

Description

A code injection vulnerability in the binary-parser library prior to version 2.3.0 allows arbitrary JavaScript code execution when untrusted values are used in parser field names or encoding parameters. The library directly interpolates these values into dynamically generated code without sanitization, enabling attackers to execute arbitrary code in the context of the Node.js process.

Analysis

Unsafe code generation in binary-parser prior to version 2.3.0 allows remote code execution when processing untrusted input for parser field names or encoding parameters. Node.js applications using vulnerable versions of the library can be compromised to execute arbitrary JavaScript with process-level privileges. …
