OpenSSF/OSV advisory MAL-2026-13369 confirms this npm version as malicious. kepler@2.0.999 declares its only runtime dependency, flag-serial-object-syntax, as an HTTP URL to a third-party host (https://artifacts.yosiroute.com/npm/flag-serial-object-syntax) rather than a version resolved from the npm registry, and the shrinkwrap marks that dependency with hasInstallScript: true.

Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** Installing kepler fetches a remote direct dependency whose shrinkwrap metadata declares an install script. The package itself contains no executable attack logic. - **Trigger:** npm installation - **Impact:** Unverified install-time code may run from the remote dependency. - **Evidence paths:** package.json, npm-shrinkwrap.json, index.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T19:35:05.999Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** remote dependency with declared install hook - **Rationale:** kepler contains no direct malicious code, but it deliberately pins an opaque remote dependency that is declared to execute during installation. This is a concrete unresolved install-time payload risk. - **Files touched:** package.json, npm-shrinkwrap.json, index.js, README.md - **Network endpoints:** https://artifacts.yosiroute.com/npm/flag-serial-object-syntax ### Review decision - **Verdict:** Suspicious - **Confidence:** 87.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for AI warning decision:** package.json declares a direct dependency from artifacts.yosiroute.com., npm-shrinkwrap.json marks that remote dependency hasInstallScript: true., The installed dependency source is absent, so its install behavior cannot be verified. - **Evidence against:** package.json has no package lifecycle scripts., index.js only exports static name/version data., No package-owned file/network/child-process behavior was found. ## Affected versions and remediation This report applies to kepler@99.99.99. - Avoid installing kepler@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.
