rollup-plugin-polyfill-helper@1.0.4

Package presents itself as a rollup plugin for CDN SVG icons, but its exported functions getPlugin/setPlugin/getPluginExten issue an HTTP request to a hardcoded remote endpoint at https://rest-icon-helper.store/icons/303 (and /icons/389) and pass the response body directly to eval(JSON.parse(b)), granting whatever the remote host serves arbitrary code execution in the caller's process. The destination URL is not written as a plain literal; it is reconstructed at runtime from split constants (protocol, separator, subdomain 'rest-icon-helper', domain 'store', path '/icons/', numeric token) via a template string. Execution is platform-gated with process.platform === 'win32' via isPlugin(): on non-Windows the remote fetch fires immediately and a follow-up getPluginExten is scheduled 60 seconds later; on Windows getPluginExten runs directly. The stated rollup-polyfill/SVG-icon purpose is unrelated to the fetch-and-eval behavior and does not appear elsewhere in the module. ## Source: ghsa-malware (58f0559ad4447885bd5ef3581be2e97da6b7c82cff4c628e1e22606cb91d0228) Any computer that has this package installed or running should be considered fully compromised.
