Provenance

Supply chain provenance

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, so a manually published version cannot be tied back to a reviewed commit.

Accepted risks

Findings the reviewer chose to accept rather than block on.

SourceRuleReasonAccepted byWhen
npm-metadata bundled-binaries AI (npm-metadata): Standard wasm-pack build artifact for native binding, not a backdoor. ai

source-diff obfuscated-file:wasm/stack_auth_wasm_inline.js AI (source-diff): Base64-embedded wasm bytes from documented inline-wasm build script, not obfuscation. ai

semgrep semgrep:new-function-constructor AI (semgrep): wasm-bindgen generated glue code pattern for WASM instantiation. ai

v0.42.0

3 findings
HIGH Bundled binary files (1) npm-metadata

Package contains compiled binaries that could be backdoors: • wasm/stack_auth_wasm_bg.wasm

HIGH Long encoded string in modified file: wasm/stack_auth_wasm_inline.js source-diff

Modified file contains 1 long encoded string(s) (200+ chars). These are commonly used to hide malicious payloads.

LOW No provenance attestation provenance

Package was published without Sigstore provenance. Consider requesting the maintainer enable provenance via CI/CD.

v0.41.0

4 findings
HIGH Publisher changed: cs-zcjbrewer → GitHub Actions (on 2026-07-06) provenance

This version was published by a different npm account than previous versions on 2026-07-06. This could indicate a legitimate maintainer transition or an account compromise.

HIGH New file with network + code execution: wasm/stack_auth_wasm_bg.js source-diff

Newly added file contains both network calls and dynamic code execution. This is a hallmark of dropper/loader malware.

HIGH New obfuscated file: wasm/stack_auth_wasm_inline.js source-diff

Newly added source file contains lines over 3000 chars, suggesting minified or obfuscated code. New obfuscated files are a strong attack indicator.

LOW No provenance attestation provenance

Package was published without Sigstore provenance. Consider requesting the maintainer enable provenance via CI/CD.
