Summary

Malicious code in @bx-ui-framework/microfrontend (npm)

Details

-= Per source details. Do not edit below this line.=-

Source: amazon-inspector (e1680cbcfbae85350989b4d123a117deb73e45aad1ee7aa339cdcef34d3fbe30)

package.json declares a runtime dependency microfrontend whose source is a bare HTTPS URL at https://repo.artifactorymanager.com/bx-ui-framework/microfrontend rather than a version on the npm registry. The URL carries no version, commit, or hash pin, so npm install fetches whatever tarball is currently served at that location and executes any lifecycle scripts and code it contains inside the installer's dependency tree. The artifactorymanager.com domain is unrelated to any established publisher for this scope, and the tarball contents can change at any time without a version bump.

CWE

CWE-506 - The product contains code that appears to be malicious in nature.
