Status for the latest visible version.

No SLSA provenance npm registry signatures No source commit

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
publish-pattern rapid-publish AI (publish-pattern): Automated publishing pipeline for a frequently-released package; rapid publishes are expected behavior here. ai
provenance missing-githead AI (provenance): High-velocity package with 319 versions; occasional missing gitHead is consistent with CI pipeline changes, not malicious activity. ai
source-diff large-new-source-files AI (source-diff): 570 new files correspond to added Word/DOCX module functionality; consistent with the package's documented scope. ai
source-diff obfuscated-file:dist/esm/modules/excel/chart/chart-sidecar.js AI (source-diff): Readable compiled TypeScript output; long lines from minified build artifact, not obfuscation. ai
source-diff obfuscated-file:dist/browser/modules/excel/chart/chart-sidecar.js AI (source-diff): Readable compiled TypeScript output; long lines from minified build artifact, not obfuscation. ai
source-diff obfuscated-file:dist/cjs/modules/excel/chart/chart-sidecar.js AI (source-diff): Readable compiled TypeScript output; long lines from minified build artifact, not obfuscation. ai
source-diff encoded-string-file:dist/browser/excelts.iife.js AI (source-diff): Long hex strings are Diffie-Hellman prime constants from the bundled diffie-hellman npm package (primes.json). These are well-known cryptographic constants, not obfuscated payloads. Will appear in every browser bundle build. ai
