No user action is required beyond installing the package. - **Trigger:** npm runs the postinstall hook during package installation. - **Impact:** Installation discloses host and user environment metadata to an unrelated external recipient. - **Evidence paths:** package.json, index.js - **Review source:** ai\_review - **Reviewed:** 2026-09-22T09:52:15.713Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** index.js collects local system metadata and sends it in an HTTPS POST request to a webhook.site endpoint. - **Attack narrative:** Installing the package invokes index.js through postinstall. That file collects the machine hostname, current account name, platform, architecture, working directory, Node version, and lifecycle event, serializes them, and sends them to a fixed webhook.site URL. This is unconsented install-time data exfiltration. - **Rationale:** The package has a concrete automatic postinstall exfiltration path to an unrelated webhook endpoint. The collected host and user metadata is sent without user interaction or package-aligned purpose. - **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 through a postinstall hook., The entrypoint gathers host name, local user name, platform, architecture, working directory, Node version, and lifecycle-event data., The entrypoint POSTs that gathered data to an unrelated webhook.site URL when it runs. ## Affected versions and remediation This report applies to @woodpecker-web-shared/components@4.20.5. - Avoid installing @woodpecker-web-shared/components@4.20.5. 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.
