Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Blocked & quarantined** — Local files and environment values, potentially including secrets, are disclosed to the webhook recipient. - **Verdict:** Malicious - **Product-default install policy:** Block - **Firewall policy:** Block by default - **Public report status:** Published - **Threat category:** Data Exfiltration - **Selected version:** 3.0.10 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) LPM AI independently confirmed malicious behavior in this version and supplies the Firewall block. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. The build action performs broad local data collection and transmits it to a fixed external webhook without a consent guard. This is concrete data exfiltration behavior and warrants blocking publication. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-10-28T22:21:09.079Z - **Finished:** 2026-10-28T22:21:34.309Z - **Download time:** 260 ms - **Static scan time:** 5 ms - **AI review time:** 24964 ms - **Total time:** 25230 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 package's native build action collects file contents and environment data, then sends them to a fixed external endpoint. This creates an installation-time data disclosure path. - **Trigger:** Installing the package invokes npm's default native build because the manifest enables gyp, a binding.gyp file is present, and no install script is defined. - **Impact:** Local files and environment values, potentially including secrets, are disclosed to the webhook recipient. - **Evidence paths:** package.json, binding.gyp - **Review source:** ai\_review - **Reviewed:** 2026-10-28T22:21:34.309Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The build action runs shell commands to enumerate directories, concatenate files, and read environment variables, then posts the results over HTTPS. - **Attack narrative:** During the default native build path, a package build action gathers directory listings, file contents, and environment variables, then posts the results to a fixed webhook endpoint. This exposes potentially sensitive local data during installation. - **Rationale:** The build action performs broad local data collection and transmits it to a fixed external webhook without a consent guard. This is concrete data exfiltration behavior and warrants blocking publication. - **Files touched:** package.json, binding.gyp - **Network endpoints:** https://webhook.site/f604623f-fc78-4447-9225-6772f7f12cb1 ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The manifest enables gyp and defines no install script, allowing npm's default native build path., The build file declares an action target that runs a Node command., The command reads directory listings, files under system and user directories, and sorted environment variables., The collected data is posted to a fixed webhook.site endpoint. ## Affected versions and remediation This report applies to spectral-core@3.0.10. - Avoid installing spectral-core@3.0.10. 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.
