It injects missing peer dependencies from a detached delayed process, outside the package directory. - **Trigger:** npm install - **Impact:** Unconsented dependency injection and alteration of the consumer project. - **Evidence paths:** package.json, scripts/postinstall.cjs, dist/chunks/Env-DRXhvUcb.js, dist/utils/index.js - **Review source:** ai\_review - **Reviewed:** 2026-08-17T10:45:40.130Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall child-process mutation of consumer manifest - **Attack narrative:** The postinstall hook identifies the consumer project through INIT\_CWD or node\_modules ancestry, creates its package.json if absent, then launches a detached Node child. After a delay, the child adds every missing peer dependency to the consumer manifest and writes it back. This is an unconsented install-time mutation of a foreign project, with delayed and detached execution that makes the change less visible. - **Rationale:** The package performs concrete, unconsented postinstall mutation of the consuming project's dependency manifest through a detached delayed process. No exfiltration was found, but the install hook itself is harmful and unjustified for a component library. - **Files touched:** scripts/postinstall.cjs, package.json, INIT\_CWD/package.json ### Review decision - **Verdict:** Malicious - **Confidence:** 96.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** package.json runs scripts/postinstall.cjs on npm install., The hook creates the consumer project's package.json if absent., A detached, unref'ed child waits 1.5 seconds before modifying the consumer manifest., The child silently adds every package peerDependency missing from consumer dependencies. - **Evidence against:** No credential harvesting, exfiltration, or install-time network request appears in the hook., Runtime fetch helpers are component utilities using caller-supplied URLs or same-origin /env.json. ## 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 scripts/postinstall.cjs ``` ### 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 scripts/postinstall.cjs ``` ### 3. Low: Non Install Lifecycle Scripts - **Category:** Manifest - **Confidence:** 80.0% Package declares lifecycle scripts that are not normally run for registry tarball installs. ### 4. Low: Scripts Present - **Category:** Manifest - **Confidence:** 100.0% Package declares npm scripts. ### 5. Medium: Network - **Category:** Source - **Confidence:** 75.0% Package source references network APIs. ### 6. Medium: Environment Vars - **Category:** Source - **Confidence:** 75.0% Package source references environment variables. ### 7. Low: Filesystem - **Category:** Source - **Confidence:** 70.0% Package source references filesystem APIs. ### 8. Low: High Entropy Strings - **Category:** Supply Chain - **Confidence:** 55.0% Package source contains high-entropy string patterns. ### 9. Low: Url Strings - **Category:** Supply Chain - **Confidence:** 65.0% Package source contains URL literals. ### 10. Medium: Structural Risk Force Deep Review - **Category:** Artifact Inventory - **Confidence:** 70.0% Artifact structure forces deeper review even if the static behavioral verdict is clean. ### 11. High: Suspicious Lifecycle Evidence - **Category:** Manifest - **Confidence:** 96.0% - **Path:** package.json - **Public source:** [View source]() package.json runs scripts/postinstall.cjs on npm install.
