Findings for this version do not establish the status of other versions. AI assessment: manual review; recommendation: manual review. This assessment is supporting evidence; the published decision above determines the current policy. The inspected postinstall path is browser setup and has a skip-download setting. The required puppeteer-core runtime dependency was unresolved in the supplied snapshot, so its behavior cannot be assessed from source and a clean verdict is not supported. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Manual Review - **Recorded analysis confidence:** 87.0% - **Started:** 2026-10-22T11:54:40.337Z - **Finished:** 2026-10-22T11:55:45.242Z - **Download time:** 780 ms - **Static scan time:** 29 ms - **AI review time:** 64095 ms - **Total time:** 64905 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:** No attack was identified in the inspected source. Review remains incomplete because a pinned runtime dependency could not be resolved for source inspection. - **Trigger:** The package postinstall hook runs the browser installer. - **Impact:** The available source does not establish malicious behavior, but the unresolved dependency prevents a complete source-based assessment. - **Evidence paths:** package.json, lib/puppeteer/node/install.js, lib/puppeteer/node/cli.js - **Review source:** ai\_review - **Reviewed:** 2026-10-22T11:55:45.242Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The installer calls the browser download routine; it also imports revision data from the unresolved puppeteer-core dependency. - **Rationale:** The inspected postinstall path is browser setup and has a skip-download setting. The required puppeteer-core runtime dependency was unresolved in the supplied snapshot, so its behavior cannot be assessed from source and a clean verdict is not supported. - **Files touched:** package.json, install.mjs, lib/puppeteer/node/install.js, lib/puppeteer/node/cli.js ### Review decision - **Verdict:** Manual Review - **Confidence:** 87.0% - **Recommended action:** manual\_review - **Intent class:** Unknown - **False-positive risk:** Medium - **AI review observations:** The manifest declares a postinstall hook that runs the installer., The installer calls the browser download routine, which honors a skip-download setting., The manifest pins puppeteer-core, and both the installer and CLI import it; its source was unresolved in the supplied dependency snapshot. - **Evidence against:** The inspected install path performs browser setup and provides a setting to skip downloads; no attack behavior was identified in the inspected excerpts. ## Affected versions and remediation This report applies to puppeteer@25.16.0. - Review the evidence and your use of puppeteer@25.16.0 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.
