What is MAL-2026-14030?
MAL-2026-14030 is a malicious package in bootstrap-custom-ui, published on 14 Aug 2026.
Official description
The package presents itself as a React/Bootstrap UI component library but its default export getPlugin performs an HTTPS request to the hardcoded bare-IP endpoint https://31.97.137.157:45000/icons/108 and passes the response's credits field to the Function constructor with full Node context (require, module, exports, process, Buffer). Any caller invoking the exported function grants the remote server arbitrary code execution on the host. The destination URL is assembled from split string fragments (protocol, separator, domain, path, token) and a decoy setDefaultModule references legitimate CDN names (cloudflare, fastly, akamai, cloudfront) that are never actually used, camouflaging the real bare-IP destination. Behavior does not match the advertised purpose.
What should I do about MAL-2026-14030?
Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
