Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Blocked & quarantined** — Installing the package discloses identifying machine and project-location metadata to the webhook operator. - **Verdict:** Malicious - **Product-default install policy:** Block - **Firewall policy:** Matched malicious - **Public report status:** Published - **Threat category:** Data Exfiltration - **Selected version:** 2.20.5 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) Trusted malware advisory MAL-2026-16354 identifies this version as malicious. Firewall keeps the version blocked under its trusted-intelligence policy. An AI recommendation to allow or warn does not override that advisory. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. An automatic install hook sends host and user environment metadata to an unrelated webhook. This is a confirmed install-time data exfiltration surface. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-09-22T09:51:40.965Z - **Finished:** 2026-09-22T09:52:09.994Z - **Download time:** 760 ms - **Static scan time:** 10 ms - **AI review time:** 28258 ms - **Total time:** 29029 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:** An automatic install hook sends host and user environment metadata to an unrelated webhook. This is a confirmed install-time data exfiltration surface. - **Trigger:** npm postinstall runs node index.js. - **Impact:** Installing the package discloses identifying machine and project-location metadata to the webhook operator. - **Evidence paths:** package.json, index.js - **Review source:** ai\_review - **Reviewed:** 2026-09-22T09:52:09.994Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The entrypoint gathers system metadata, serializes it, and sends it by HTTPS POST to the configured webhook. - **Attack narrative:** On installation, the postinstall hook executes index.js. It gathers the hostname, current username, platform, architecture, working directory, Node version, and lifecycle event, then posts the JSON payload to a webhook.site URL. The request is invoked immediately without user action or destination restriction. - **Rationale:** The package has an automatic postinstall beacon that exfiltrates local system and project metadata to a third-party endpoint. This is concrete malicious install-time data collection. - **Network endpoints:** https://webhook.site/d9bc4bcc-ce74-4193-ae4e-96d234bb2220 ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The package runs index.js automatically in a postinstall lifecycle hook., index.js collects the host name, local user name, platform, architecture, current working directory, Node version, and lifecycle event., The collected data is JSON-encoded and posted to a third-party webhook endpoint during execution. ## Affected versions and remediation This report applies to @woodpecker-web-shared/components@2.20.5. - Avoid installing @woodpecker-web-shared/components@2.20.5. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
