The dependency is additionally force-loaded on require: `lib/cache.js` top-level calls `module['require']('node-net-pool')` inside a try/catch, so importing mfasolver also executes the attacker-controllable code. Separately, `index.js` opens TLS connections to discord.com with `rejectUnauthorized: false`, disabling certificate validation on the package's own Discord traffic.","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 mfasolver (npm)","id":"MAL-2026-17663","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":"mfasolver","purl":"pkg:npm/mfasolver","source":"MAL-2026-17663"}],"products":null,"published":"2026-10-08","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-2026-17663/"}
