Accepted risks

Findings the reviewer chose to accept rather than block on.

SourceRuleReasonAccepted byWhen
source-diff encoded-string-file:dist/react-app.umd.production.min.js AI (source-diff): Long encoded strings are expected in webpack UMD minified bundles for this genomics visualization library; stable false positive. ai
source-diff net-exec-file:dist/react-app.umd.production.min.js AI (source-diff): UMD production bundle for a genomics app; network+eval patterns are from CSS-in-JS and worker infrastructure, not malware. ai
source-diff source-size-tripled AI (source-diff): Size increase reflects bundling all @jbrowse plugins into a UMD dist; expected for this package type. ai
provenance publisher-changed AI (provenance): Transition to GitHub Actions CI publishing with SLSA attestation is a legitimate supply-chain improvement. ai
phantom-deps phantom-dep:@emotion/cache AI (phantom-deps): Declared as peer/transitive dep for MUI theming; config-file reference is expected pattern. ai
provenance no-provenance AI (provenance): Established JBrowse monorepo; lack of provenance is common and not a risk signal here. ai
phantom-deps phantom-dep:@emotion/react AI (phantom-deps): MUI requires @emotion/react; config-file reference is standard. ai
phantom-deps phantom-dep:@emotion/styled AI (phantom-deps): MUI requires @emotion/styled; config-file reference is standard. ai
phantom-deps phantom-dep:@types/file-saver-es AI (phantom-deps): Type-only package; framework-scoped, not directly imported at runtime. ai

v4.3.0

2 findings
HIGH Long encoded string in modified file: dist/react-app.umd.production.min.js source-diff

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

INFO Has SLSA provenance attestation provenance

Published via CI/CD with Sigstore attestation (predicate: https://slsa.dev/provenance/v1). This is the strongest supply chain integrity signal.

v4.2.1

3 findings
HIGH Publisher changed: cmdcolin → GitHub Actions (on 2026-04-27) provenance

This version was published by a different npm account than previous versions on 2026-04-27. This could indicate a legitimate maintainer transition or an account compromise.

HIGH New file with network + code execution: dist/react-app.umd.production.min.js source-diff

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

INFO Has SLSA provenance attestation provenance

Published via CI/CD with Sigstore attestation (predicate: https://slsa.dev/provenance/v1). This is the strongest supply chain integrity signal.

v4.1.15

2 findings
HIGH New file with network + code execution: dist/react-app.umd.production.min.js source-diff

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

INFO No provenance attestation provenance

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

v4.1.1

1 finding
LOW No provenance attestation provenance

Package was published without Sigstore provenance. Only ~12% of npm packages have provenance, so this is common but not ideal.

v4.0.4

1 finding
LOW No provenance attestation provenance

Package was published without Sigstore provenance. Only ~12% of npm packages have provenance, so this is common but not ideal.

v4.0.3

1 finding
LOW No provenance attestation provenance

Package was published without Sigstore provenance. Only ~12% of npm packages have provenance, so this is common but not ideal.

v4.0.2

1 finding
LOW No provenance attestation provenance

Package was published without Sigstore provenance. Only ~12% of npm packages have provenance, so this is common but not ideal.
