Every version was published to cause harm.\n\nTask:\n1. Search this repository's dependency manifests and lockfiles for the package, including transitive dependencies.\n2. 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 fetched JavaScript executes with full DOM and same-origin access in any site that uses the component. The source is a bare IPv4 address over cleartext HTTP at a mutable `/Dev/` path with no Subresource Integrity, no version pinning, and no TLS — whoever controls that IP, and any on-path network attacker, can serve arbitrary JavaScript into the consumer's application. Additionally, `window.MetricflowConfig.collectUrl` defaults to `http://51.38.65.105:21531/collect`, silently relaying end-user telemetry collected by the loaded tracker to the same hardcoded host. Package metadata provides no author, homepage, or documentation tying that IP to a legitimate analytics vendor. The combination of remote-code-loading from an unverified mutable HTTP endpoint plus silent relay of end-user data to an opaque destination is supply-chain harm to any installer that renders this component.","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 metricflow-tracker (npm)","id":"MAL-2026-4805","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":"metricflow-tracker","purl":"pkg:npm/metricflow-tracker","source":"MAL-2026-4805"}],"products":null,"published":"2026-05-26","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-2026-4805/"}
