Advisory published Updated

Malicious code in golan125-homepage-test (npm)
What this malware does
Package self-identifies as a security research test ('Security research test - do not install'). The package.json homepage field contains javascript:alert(document.domain), which is an XSS probe targeting any registry or UI frontend that renders homepage values as clickable links without sanitization. The package has no lifecycle scripts (no preinstall/install/postinstall), no network I/O, and index.js exports an empty object — installing or requiring this package does not harm the installer's machine. The XSS probe targets registry web UI rendering, not developers who install the package.

Malicious packageFind it
Search your lockfiles and build artifacts for golan125-homepage-test (version 1.0.0).
If you installed it — respond
Remove golan125-homepage-test from your project and lockfile, then assume any secrets accessible to the build or runtime were exposed: rotate API keys, tokens, and credentials, and audit for unexpected outbound activity or persistence.
Did it already run?
If golan125-homepage-test was installed, its post-install payload may already have run. Removing the package does not undo that — check outbound connections and credential use from the install window onward.
