The seeded workflow can publish to npm and push commits when later triggered in GitHub Actions. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 91.0% - **Started:** 2026-08-09T17:11:12.160Z - **Finished:** 2026-08-09T17:12:10.942Z - **Download time:** 1020 ms - **Static scan time:** 98 ms - **AI review time:** 57662 ms - **Total time:** 58782 ms ## Security analysis ### Published attack-surface review - **Summary:** Install-time code seeds a consumer repository's configuration and CI/release pipeline. The seeded workflow can publish to npm and push commits when later triggered in GitHub Actions. - **Trigger:** npm install or npm ci of the package - **Impact:** Unconsented project and CI control-plane modification; later workflow execution can use the consumer's NPM secret and repository write permission. - **Evidence paths:** package.json, src/postinstall.js, src/pipeline/release.yml, src/pipeline/verify-npm-token.yml, README.md - **Review source:** ai\_review - **Reviewed:** 2026-08-09T17:12:10.942Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall copies absent project files and GitHub Actions workflows - **Rationale:** The package has a real, broad install-hook capability that mutates consumer CI/release configuration, including a token-backed publishing workflow. It is transparent and package-aligned rather than concrete malware, so warning is appropriate. - **Files touched:** package.json, .github/workflows/release.yml, .github/workflows/verify-npm-token.yml, .changeset/config.json, scripts/auto-changeset.sh, eslint.config.js, tsconfig.json, prettier.config.js, docs/assets/doikayt-logo.png, docs/assets/doikayt-logo.svg - **Network endpoints:** https://registry.npmjs.org, https://unpkg.com/@changesets/config@3.1.2/schema.json ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Unknown - **False-positive risk:** Medium - **Evidence for:** package.json runs src/postinstall.js automatically., src/postinstall.js writes project-root files and GitHub workflows., src/pipeline/release.yml grants contents: write and publishes with secrets.NPM., The release workflow commits and pushes generated changes. - **Evidence against:** Behavior is plainly documented in README.md., Postinstall only creates absent pipeline/config files and does not overwrite diverged files., No credential harvesting, exfiltration, remote payload loading, or obfuscated code found., Playwright shell-out is an explicit bin, not import/install execution. ## Public findings ### 1. High: Install Time Lifecycle Scripts - **Category:** Manifest - **Confidence:** 90.0% - **Path:** package.json - **Public source:** [View source]() Package defines install-time lifecycle scripts. Public source snippet (untrusted): ```json scripts.postinstall = node src/postinstall.js ``` ### 2. Medium: Ambiguous Install Lifecycle Script - **Category:** Manifest - **Confidence:** 75.0% - **Path:** package.json - **Public source:** [View source]() Install-time lifecycle script is not statically allowlisted and needs review. Public source snippet (untrusted): ```json scripts.postinstall = node src/postinstall.js ``` ### 3. Low: Scripts Present - **Category:** Manifest - **Confidence:** 100.0% Package declares npm scripts. ### 4. Medium: Environment Vars - **Category:** Source - **Confidence:** 75.0% Package source references environment variables. ### 5. Low: Filesystem - **Category:** Source - **Confidence:** 70.0% Package source references filesystem APIs. ### 6. Medium: Ships Build Helper - **Category:** Artifact Inventory - **Confidence:** 70.0% - **Path:** src/pipeline/auto-changeset.sh - **Public source:** [View source]() Package ships non-JavaScript build or shell helper files. Public source snippet (untrusted): ```shell path = src/pipeline/auto-changeset.sh kind = build_helper sizeBytes = 2940 magicHex = [redacted] ``` ### 7. High: Ships High Entropy Blob - **Category:** Artifact Inventory - **Confidence:** 75.0% - **Path:** assets/jews-support-a-free-palestine-poster.pdf - **Public source:** [View source]() Package ships high-entropy non-source blobs. Public source snippet (untrusted): ```text path = assets/jews-support-a-free-palestine-poster.pdf kind = high_entropy_blob sizeBytes = 1040003 magicHex = [redacted] ``` ### 8. Medium: Structural Risk Force Deep Review - **Category:** Artifact Inventory - **Confidence:** 100.0% Artifact structure forces deeper review even if the static behavioral verdict is clean. ## Dependencies and install lifecycle - **Lifecycle scripts present:** Yes - **Published lifecycle scripts:** postinstall - **Dependencies:** 4 - **Optional dependencies:** 0 - **Peer dependencies:** 3 - **Development dependencies:** 3 - **Published dependency-graph edges:** 7 ### Published dependency entries - @typescript-eslint/eslint-plugin ^8.0.0 (Dependency) - @typescript-eslint/parser ^8.0.0 (Dependency) - eslint ^9.0.0 (Dependency) - prettier ^3.0.0 (Dependency) - @playwright/test \>=1.40.0 (PeerDependency) - @typescript-eslint/eslint-plugin ^8.57.1 (PeerDependency) - @typescript-eslint/parser ^8.57.1 (PeerDependency) ## Package metadata - **Package:** @doikayt/typescript-build-config - **Ecosystem:** npm - **Version:** 0.1.16 - **License:** MIT - **Version published:** 2026-08-09T07:36:14.415Z - **Package first seen:** 2026-07-27T08:18:40.166Z - **Package last seen:** 2026-08-11T10:03:54.840Z - **Known versions:** 13 - **Latest version:** 0.1.31 - **Appeal under review:** No - **Description:** Shared build configuration for TypeScript projects — ESLint, Prettier, tsconfig, and Playwright presets - **Maintainers:** datalackey - **Keywords:** eslint, typescript, config, build, tooling, playwright - **Runtime engines:** node: \>=22 - **Artifact files:** 40 - **Artifact unpacked size:** 5,238,209 bytes - **Artifact signatures:** 1 - **Attestations:** No ## References - [HTML security report]() - [Repository]() - [Homepage]() - [Issues]()
