Summary
Malicious code in sentrykit (npm)
Details
package.json declares a self-referential dependency where the key `sentrykit` maps to the bare HTTPS URL `https://repo.securityctrl.com/sentrykit` instead of a registry version range. On `npm install`, npm fetches whatever tarball that URL returns and installs it, running any lifecycle scripts contained in the fetched artifact. The source is unpinned, integrity-unchecked, and not the official npm registry; the shipped package body is a one-line stub, so the manifest itself is the entire delivery mechanism. The dependency key equals the package's own name and the version constraint (30.0.0) is implausibly high for a package of this size, matching the dependency-confusion smuggling shape where a high version number is used to win resolution against an internal package of the same name. Whoever controls repo.securityctrl.com controls code executed on the installer's machine at install time.
