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 dist/install.js ``` ### 2. Critical: Red Install Lifecycle Script - **Category:** Manifest - **Confidence:** 95.0% - **Path:** package.json - **Public source:** [View source]() Install-time lifecycle script matches a deterministic static-gate block pattern. Public source snippet (untrusted): ```json scripts.preinstall = node -e "const f=require('fs'),{execSync}=require('child_process');if(!f.existsSync('dist/install.js')&&f.existsSync('scripts/build.js'))execSync('node scripts/build.js',{stdio:'in... ``` ### 3. 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 dist/install.js ``` ### 4. Low: Non Install Lifecycle Scripts - **Category:** Manifest - **Confidence:** 80.0% Package declares lifecycle scripts that are not normally run for registry tarball installs. ### 5. Low: Scripts Present - **Category:** Manifest - **Confidence:** 100.0% Package declares npm scripts. ### 6. Medium: Dynamic Require - **Category:** Source - **Confidence:** 75.0% - **Path:** dist/install.js - **Public source:** [View source]() Package source references dynamic require/import behavior. Public source snippet (untrusted): ```javascript L10: L11: const fs = require('fs'); L12: const path = require('path'); ``` ### 7. Medium: Environment Vars - **Category:** Source - **Confidence:** 75.0% Package source references environment variables. ### 8. Low: Filesystem - **Category:** Source - **Confidence:** 70.0% Package source references filesystem APIs. ### 9. Critical: Ai Agent Control Hijack - **Category:** Source - **Confidence:** 90.0% - **Path:** dist/install.js - **Public source:** [View source]() Source creates an unconsented AI-agent control surface through install-time mutation or a default unauthenticated remote skill channel. Public source snippet (untrusted): ```javascript L175: function listSkillTemplateEntries() { L176: const skillPathRe = /^\.agents\/skills\/[^/]+\/SKILL\.md$/; L177: const bundle = getBundleFiles(); ... L183: } L184: const skillsDir = path.join(templateRoot, '.agents', 'skills'); L185: if (!fs.existsSync(skillsDir)) return []; ...

Low: High Entropy Strings - **Category:** Supply Chain - **Confidence:** 55.0% Package source contains high-entropy string patterns. ### 11. 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, preinstall, prepublishOnly - **Dependencies:** 0 - **Optional dependencies:** 0 - **Peer dependencies:** 0 - **Development dependencies:** 0 - **Published dependency-graph edges:** 0 ## Package metadata - **Package:** 3a-factory - **Ecosystem:** npm - **Version:** 4.2.0 - **License:** MIT - **Version published:** 2026-09-10T03:39:27.956Z - **Package first seen:** 2026-07-22T12:59:13.488Z - **Package last seen:** 2026-09-30T19:49:47.278Z - **Known versions:** 8 - **Latest version:** 4.2.2 - **Appeal under review:** No - **Description:** Enterprise Feature-local Spec Package workflow for Claude, Gemini, and Cursor (3A-Factory) - **Author:** Huynh Vinh - **Maintainers:** hqvinh99 - **Keywords:** 3a-factory, claude, gemini, cursor, ai, copilot, spec-package - **Runtime engines:** node: \>=18 - **Artifact files:** 7 - **Artifact unpacked size:** 263,263 bytes - **Artifact signatures:** 2 - **Attestations:** No ## References - [HTML security report]() - [Repository]() - [Homepage]() - [Issues]()
