Background
The subtext package is an npm package that is used for parsing and handling multipart HTTP requests. It allows developers to extract and process data from multipart payloads. However, all versions of subtext are vulnerable to Prototype Pollution.
Vulnerability Detail
Prototype Pollution is a vulnerability that occurs when an attacker can inject properties into existing objects, including JavaScript's built-in objects and functions. In the case of subtext, a multipart payload can be constructed in a way that one of the parts' content can be set as the entire payload object's prototype. This means that the attacker can manipulate the prototype to bypass validation rules and potentially access or modify sensitive data. Additionally, if the prototype evaluates to null, it can cause unhandled exceptions when the request payload is accessed.
How To Fix
No fixed version is published for this vulnerability.
