Status for the latest visible version.

No SLSA provenance npm registry signatures gitHead linked

Without SLSA provenance there is no cryptographic link between this tarball and the public source — the axios compromise (March 2026) relied on exactly this gap.

Accepted risks

Findings the reviewer chose to accept rather than block on.

SourceRuleReasonAccepted byWhen
maintainer-change maintainer-added AI (maintainer-change): jakub-g was added as maintainer in 2015; this is a stable, long-standing legitimate ownership state. ai
maintainer-change maintainer-removed AI (maintainer-change): ariatemplates removal is part of the 2015 legitimate ownership transfer; no ongoing risk. ai
maintainer-change maintainer-takeover AI (maintainer-change): Publisher change occurred in Jan 2015 (~10 years ago); jakub-g has 8 approved packages, repo URL matches publisher identity, and no malicious signals have ever materialized. Legitimate historical transfer. ai
provenance publisher-changed AI (provenance): Publisher change to jakub-g happened in 2015; consistent with repo ownership and long-standing clean track record. Not an active risk. ai
semgrep semgrep:child-process-import AI (semgrep): x-default-browser uses child_process to run system commands (e.g., xdg-settings) to detect the default browser on Linux — this is core to the package's documented purpose and not a security risk. ai

v0.3.1

3 findings
HIGH Complete maintainer takeover detected maintainer-change

All previous maintainers (ariatemplates) were replaced by new maintainers (jakub-g). This is a strong signal of a potential package hijack and requires careful review.

HIGH Publisher changed: ariatemplates → jakub-g (on 2015-11-19) provenance

This version was published by a different npm account than previous versions on 2015-11-19. This could indicate a legitimate maintainer transition or an account compromise.
