Understanding filesystem takeover vulnerabilities in npm JavaScript package manager
Blog post from Snyk
The npm package manager client is vulnerable to a security vulnerability that allows arbitrary file overwrites, which can be exploited by malicious actors to overwrite files in the user's filesystem or project directory. This vulnerability affects packages installed globally and transitive dependencies, and can lead to inject malware, alter lockfiles, or poison the filesystem. The vulnerability is severe because it can occur even when using the `ignore-scripts` flag, and has triggered Node.js security releases. Users are advised to upgrade to fixed versions of npm, yarn, and pnpm, and practice secure developer practices to mitigate this risk.
