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
provenance publisher-changed AI (provenance): Publisher 'nv' is the original author (Nikita Vasilyev / NV/CSSOM). Change from 'domenic' to 'nv' is the author resuming publishing under their own account. ai
provenance no-provenance AI (provenance): Published in 2017, before Sigstore provenance existed. Expected for this era of packages. ai
typosquat typosquat.levenshtein:jsdom AI (typosquat): cssom is a legitimate, well-known CSS Object Model package (52M+ weekly downloads, 5295 days old). The name is a standard acronym unrelated to jsdom; Levenshtein match is a stable false positive for this package. ai
