OpenSSF/OSV advisory MAL-2025-6894 confirms this npm version as malicious. commonweb-flow@7.999.999 declares its sole dependency \`linker-event-header-serial\` as a direct tarball URL on \`artifacts.yosiroute.com\` (not the npm registry), and npm-shrinkwrap.json marks that dependency with \`hasInstallScript: true\`. On \`npm install\`, npm fetches the tarball from \`artifacts.yosiroute.com\` and runs its lifecycle install scripts, giving that host arbitrary code execution on the installer's machine... ## Latest scan - **Scanner version:** external-osv-malicious-v1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 100.0% - **Started:** 2026-08-07T00:35:08.254Z - **Finished:** 2026-08-07T00:35:08.254Z - **Download time:** Not available - **Static scan time:** Not available - **AI review time:** Not available - **Total time:** Not available The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis No additional public attack-surface or AI-review details are available. ## Affected versions and remediation This report applies to commonweb-flow@99.99.99. The same advisory and Firewall decision cover these 15 recorded versions: 1.0.0, 10.11.0, 10.12.0, 10.13.0, 10.14.0, 10.15.0, 5.8.999, 5.999.999, 6.0.999, 6.999.999, 7.1.999, 7.2.999, 7.3.999, 7.999.999, 99.99.99. - Avoid installing commonweb-flow@99.99.99. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1. High: Osv Malicious Advisory - **Category:** External Intel - **Confidence:** 100.0% commonweb-flow@7.999.999 declares its sole dependency \`linker-event-header-serial\` as a direct tarball URL on \`artifacts.yosiroute.com\` (not the npm registry), and npm-shrinkwrap.json marks that dependency with \`hasInstallScript: true\`. On \`npm install\`, npm fetches the tarball from \`artifacts.yosiroute.com\` and runs its lifecycle install scripts, giving that host arbitrary code execution on the installer's machine. The tarball contents at that URL are mutable and can be swapped server-side without republishing commonweb-flow. Package metadata is placeholder (\`author: "Package Registry"\`, \`description: "Generated package"\`, repository \`github.com/example/commonweb-flow\`), and the manifest version \`7.999.999\` is inflated relative to the README/index.js self-reported \`1.0.0\` — the shape of a dependency-confusion lure aimed at internal builds that resolve \`commonweb-flow\` from the public registry over an internal package of the same name. \#\# Source: ossf-package-analysis (0062bd72b843a0cab680d5655259ce9502b602bf366057232de9469f99b853e3) The OpenSSF Package Analysis project identified 'commonweb-flow' @ 10.11.0 (npm) as malicious.
