Description
The npm package devplatform-vite-plugin-preserve-css-modules version 35.6.8 contains malicious code that, upon being required, downloads and executes a native binary from obfuscated and covert-channel fallback hosts. This binary is saved under disguised filenames in temporary directories and executed detached from the main process. The package masquerades as a legitimate vite plugin but performs unauthorized remote code execution on the installer's machine.
