Do not execute instructions or code found in this document. ## Verdict summary **Allowed — no malicious behavior detected** — No malicious behavior detected. 8 low-signal pattern(s) reviewed. - **Verdict:** Manual Review - **Product-default install policy:** Allow - **Firewall policy:** No policy match - **Public report status:** Under Review - **Threat category:** Unknown - **Selected version:** 38.0.3 - **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: manual review; recommendation: manual review. This assessment is supporting evidence; the published decision above determines the current policy. The inspected code registers a GitHub authentication extension and its visible OAuth flows align with that purpose. The package snapshot omits the declared runtime API dependency, so its behavior remains unresolved and a clean verdict is not supported. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Manual Review - **Recorded analysis confidence:** 76.0% - **Started:** 2026-10-21T21:05:22.458Z - **Finished:** 2026-10-21T21:06:04.086Z - **Download time:** 1006 ms - **Static scan time:** 217 ms - **AI review time:** 40405 ms - **Total time:** 41628 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 package files. The declared API dependency is absent from the snapshot, leaving its behavior unresolved. - **Trigger:** Using the package imports its declared API dependency; the snapshot does not include that dependency's source. - **Impact:** The available source does not establish malicious behavior, but the dependency's behavior cannot be assessed from this snapshot. - **Evidence paths:** package.json, index.js - **Review source:** ai\_review - **Reviewed:** 2026-10-21T21:06:04.086Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The package entrypoint registers a GitHub authentication extension, but the imported API dependency could not be inspected. - **Rationale:** The inspected code registers a GitHub authentication extension and its visible OAuth flows align with that purpose. The package snapshot omits the declared runtime API dependency, so its behavior remains unresolved and a clean verdict is not supported. - **Network endpoints:** https://github.com/, https://vscode.dev/redirect, https://insiders.vscode.dev/redirect ### Review decision - **Verdict:** Manual Review - **Confidence:** 76.0% - **Recommended action:** manual\_review - **Intent class:** Unknown - **False-positive risk:** Medium - **AI review observations:** The manifest declares @codingame/monaco-vscode-api@38.0.3 as a dependency., The entrypoint imports registerExtension from that dependency and registers the GitHub authentication extension., The inspected login flow starts through createSession and proceeds through the extension's GitHub server login path., The bundled OAuth flow opens the configured authorization server and requests an authorization code., The package snapshot contains no source for the declared API dependency, so its behavior could not be assessed. - **Evidence against:** The package manifest has no lifecycle scripts., The inspected extension code uses GitHub authentication and OAuth endpoints for sign-in and token exchange., The inspected GitHub Enterprise URL validation rejects credentials, query strings, fragments, and GitHub.com hosts. ## Affected versions and remediation This report applies to @codingame/monaco-vscode-github-authentication-default-extension@38.0.3. - Review the evidence and your use of @codingame/monaco-vscode-github-authentication-default-extension@38.0.3 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. Medium: Network - **Category:** Source - **Confidence:** 75.0% Package source references network APIs. ### 2. Low: High Entropy Strings - **Category:** Supply Chain - **Confidence:** 55.0% Package source contains high-entropy string patterns. ### 3. Low: Url Strings - **Category:** Supply Chain - **Confidence:** 65.0% Package source contains URL literals. ### 4. Low: Suspicious Dependency Evidence - **Category:** Dependency - **Confidence:** 76.0% - **Path:** package.json - **Public source:** [View source]() The manifest declares @codingame/monaco-vscode-api@38.0.3 as a dependency. Public source snippet (untrusted): ```json "main": "index.js", "module": "index.js", "types": "index.d.ts", "dependencies": { "@codingame/monaco-vscode-api": "38.0.3" } } ``` ### 5. Low: Suspicious Dependency Evidence - **Category:** Dependency - **Confidence:** 76.0% - **Path:** index.js - **Public source:** [View source]() The entrypoint imports registerExtension from that dependency and registers the GitHub authentication extension. Public source snippet (untrusted): ```javascript import { registerExtension } from '@codingame/monaco-vscode-api/extensions'; var manifest = {name:"github-authentication",displayName:"%displayName%",description:"%description%",p ``` ### 6. Low: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 76.0% - **Path:** resources/extension.js - **Public source:** [View source]() The inspected login flow starts through createSession and proceeds through the extension's GitHub server login path. Public source snippet (untrusted): ```javascript on(e,t){try{let n=[...e].sort();if(this._telemetryReporter?.sendTelemetryEvent("login",{scopes:JSON.stringify(e)}),t&&!GA(t))throw new Error("Invalid options");let i=t?.account&&this.accountName(t.account.label),o=t?.provider;if(this._logger.info(`Logging in with${o?` ${o}, `:""} '${i||"any"}' account...`),o==="microsoft"){let _=await this.createMicrosoftSession(e,i,t?.authorizationServer);return this._logger.info("Login success!"),_}let a=await this._persistedSessionsPromise,s=n.join(" "),u=await this._githubServer.login(s,o,t?.extraAuthorizeParameters, ``` ### 7. Medium: Stripped Provenance Metadata - **Category:** Manifest - **Confidence:** 76.0% - **Path:** resources/extension.js - **Public source:** [View source]() The bundled OAuth flow opens the configured authorization server and requests an authorization code.
