Background
The memories-core-web package is an npm library designed for web applications, providing essential functionalities for managing user interactions and data. However, it has been found to contain a significant vulnerability that allows malicious code execution during the installation process, posing a serious risk to users and their systems.
Vulnerability Detail
The vulnerability originates from a preinstall lifecycle script defined in the package.json file of memories-core-web. This script executes a curl command that sends sensitive information, including the installer's hostname and username, to a hardcoded URL on webhook.site. This action occurs automatically during the npm install process, leading to unauthorized data transmission to a third-party collector, which is not associated with the package's publisher. The implications of this vulnerability include potential exposure of sensitive user data and compromise of system integrity.
How To Fix
This package is malicious. Remove it and rotate any credentials it could have accessed.
npm uninstall memories-core-webIf it arrived as a transitive dependency, remove the package that pulled it in, then reinstall.

Conclusion
The memories-core-web package contains a serious vulnerability that allows for the transmission of sensitive user data to an external server during installation. Users are advised to update the package to a patched version and consider workarounds to mitigate risks until an update can be applied.
