Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Allowed — no malicious behavior detected** — No malicious behavior detected. 12 low-signal pattern(s) reviewed. - **Verdict:** Clean - **Product-default install policy:** Allow - **Firewall policy:** No policy match - **Public report status:** Published - **Threat category:** None published - **Selected version:** 0.2.31 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) This is the current Firewall decision for the selected package version, based on the available public evidence. 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 package has no install lifecycle hook, and its installer, router requests, and subprocess features are tied to user-run setup or the advertised routing and language-server functions. The scanner leads are consistent with those features, not evidence of malicious behavior. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 94.0% - **Started:** 2026-10-31T20:01:29.015Z - **Finished:** 2026-10-31T20:02:19.573Z - **Download time:** 517 ms - **Static scan time:** 340 ms - **AI review time:** 49700 ms - **Total time:** 50558 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; the reviewed network and process behavior serves the router installer and pi language-server features. - **Trigger:** A user runs the CLI to install, uninstall, or change routing, or affirmatively enables a language server. - **Impact:** These actions support the package's stated purpose; no unauthorized collection or execution was identified. - **Review source:** ai\_review - **Reviewed:** 2026-10-31T20:02:19.573Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The installer configures AI clients and contacts the selected router for validation and state-change events; the pi extension can start language-server processes. - **Rationale:** The package has no install lifecycle hook, and its installer, router requests, and subprocess features are tied to user-run setup or the advertised routing and language-server functions. The scanner leads are consistent with those features, not evidence of malicious behavior. - **Network endpoints:** router.weaveos.com, raw.githubusercontent.com, auth.openai.com, console.anthropic.com ### Review decision - **Verdict:** Clean - **Confidence:** 94.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** package.json declares only a prepack script, with no install lifecycle hook., bin.js dispatches to the installer or uninstaller when a user runs the CLI., The installer validates the router key against the configured router base URL., After a successful routing toggle, the installer reports only the action and client type to the installed router., The pi extension describes language-server installation as requiring a user's affirmative response. ## Affected versions and remediation This report applies to @workweave/router@0.2.31. - Review the evidence and your use of @workweave/router@0.2.31 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.
