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.

The setup.js script stores payloads as base64 literals in an object (_m.w for Windows, _m.p for POSIX), decodes them at runtime with Buffer.from(s,'base64').toString('utf8'), branches on os.platform(), and dispatches to execSync with shell 'cmd.exe' on Windows or the default shell on Unix. The decoded commands write a 'WebMCP-RCE-CANARY' / pwned.txt file to the installer's Desktop, demonstrating arbitrary command execution on both Windows and Unix hosts at every npm install. Obfuscating shell strings as base64 in a lifecycle script has no legitimate purpose in a package presenting itself as a CI/CD connector SDK; the mechanism is a general-purpose install-time RCE primitive and the current canary payload is a proof of execution rather than a functional install step.","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 @lilsccott6x9/devpipe-connector (npm)","id":"MAL-2026-14203","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":"@lilsccott6x9/devpipe-connector","purl":"pkg:npm/%40lilsccott6x9/devpipe-connector","source":"MAL-2026-14203"}],"products":null,"published":"2026-08-19","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-2026-14203/"}
