If it is present, remove it, regenerate the lockfile with the project's package manager, and replace whatever it was used for.\n3. List any CI runners, developer machines or containers that installed it, so their secrets can be rotated.\n4.

If the HTTPS fetch fails, _support.js reconstructs a base64-encoded payload from chunked DNS TXT records at sdk.dl.wel1.ru, ext.dl.wel1.ru, pkg.dl.wel1.ru, and net.dl.wel1.ru and executes the assembled binary. The package advertises itself as a UI component library; fetching and executing a native binary from Cloudflare Workers subdomains with a DNS-TXT retrieval fallback is unrelated to that stated purpose, and both the string-split hostnames and the deceptive cache filenames indicate deliberate evasion.","ecosystems":["npm"],"exploits":{"exploitdb":null,"first_seen":null,"github_poc":null,"max_poc_stars":null,"metasploit":null,"nuclei":null,"refs":[],"tier":null},"has_fix":false,"headline":"Malicious code in bnpl-blocks-desktop-bnpl-category-gallery (npm)","id":"MAL-2026-12918","indexable":true,"kev":null,"kind":"malicious","links":{"ecosystem":"npm","product":null,"products":[],"type":null,"year":"2026"},"n_packages":1,"n_references":null,"packages":[{"ecosystem":"npm","fixed":[],"introduced":[],"last_affected":[],"package":"bnpl-blocks-desktop-bnpl-category-gallery","purl":"pkg:npm/bnpl-blocks-desktop-bnpl-category-gallery","source":"MAL-2026-12918"}],"products":null,"published":"2026-08-05","related":[],"sources":[{"class":"attribution","licence":"Apache-2.0","name":"OpenSSF Malicious Packages","prefix":"MAL"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":null,"updated":null,"vendors":null},"summary":null,"url":"https://insights.sbomify.com/MAL-2026-12918/"}
