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. If the package is not used anywhere, say so and change nothing.\n\nReference: https://insights.sbomify.com/MAL-2026-15544/ (Markdown: https://insights.sbomify.com/MAL-2026-15544/index.md)","id":"MAL-2026-15544","markdown":"https://insights.sbomify.com/MAL-2026-15544/index.md","name":"MAL-2026-15544","record":{"aliases":["GHSA-qq6h-882h-g88f"],"analysis":null,"analysis_generated_by":null,"assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"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.\n\nAny computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer.
