Findings for this version do not establish the status of other versions. AI assessment: clean; recommendation: mark clean. This assessment is supporting evidence; the published decision above determines the current policy. The postinstall behavior is browser setup for Puppeteer and honors its download configuration. The inspected entrypoints showed no separate attack behavior. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 96.0% - **Started:** 2026-10-14T04:27:41.248Z - **Finished:** 2026-10-14T04:28:09.840Z - **Download time:** 258 ms - **Static scan time:** 28 ms - **AI review time:** 28305 ms - **Total time:** 28592 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** The inspected source defines an install-time browser downloader. No attack was identified in that behavior or the inspected package entrypoints. - **Trigger:** Package installation runs the postinstall script. - **Impact:** No harmful impact was established from the inspected source. - **Review source:** ai\_review - **Reviewed:** 2026-10-14T04:28:09.840Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The script invokes Puppeteer’s configured browser installer, which installs browser builds into its cache. - **Rationale:** The postinstall behavior is browser setup for Puppeteer and honors its download configuration. The inspected entrypoints showed no separate attack behavior. ### Review decision - **Verdict:** Clean - **Confidence:** 96.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** package.json defines postinstall as node install.mjs., install.mjs invokes Puppeteer’s browser download routine., The routine reads configuration, honors the skip-download setting, and schedules browser installation., The installer passes browser, cache directory, platform, and build ID to the browser installer., The public entrypoint re-exports puppeteer-core and creates a PuppeteerNode instance. ## Affected versions and remediation This report applies to puppeteer@25.13.0. - Review the evidence and your use of puppeteer@25.13.0 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1.
