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 manifest has no install lifecycle hook, and the inspected entrypoints and runtime implementations provide message transport using caller-supplied connection inputs. No concrete attack behavior was found. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 91.0% - **Started:** 2026-10-25T16:13:49.093Z - **Finished:** 2026-10-25T16:14:22.198Z - **Download time:** 765 ms - **Static scan time:** 84 ms - **AI review time:** 32255 ms - **Total time:** 33105 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 inspected runtime code provides caller-configured socket and webview message transport for the data-server protocol. - **Trigger:** A consumer calls the exported connection or data-port APIs. - **Impact:** The code relays protocol messages for the consumer; no credential collection, unrelated account action, or package-directed egress was identified. - **Review source:** ai\_review - **Reviewed:** 2026-10-25T16:14:22.198Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The Node API connects to the supplied socket host and port; the browser API forwards messages through the supplied channel. - **Rationale:** The manifest has no install lifecycle hook, and the inspected entrypoints and runtime implementations provide message transport using caller-supplied connection inputs. No concrete attack behavior was found. ### Review decision - **Verdict:** Clean - **Confidence:** 91.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** package.json defines build and prepack scripts; no install lifecycle hook is present., The package entrypoint exports a messenger channel., The Node connection opens a socket using the supplied port and host, then relays it through the supplied channel., The browser port wraps the supplied channel in a JSON-RPC transport. ## Affected versions and remediation This report applies to @hydranium/data-client-vscode@1.0.0-next.333. - Review the evidence and your use of @hydranium/data-client-vscode@1.0.0-next.333 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. Low: Scripts Present - **Category:** Manifest - **Confidence:** 100.0% Package declares npm scripts. ### 2. Low: Suspicious Lifecycle Evidence - **Category:** Manifest - **Confidence:** 91.0% - **Path:** package.json - **Public source:** [View source]() package.json defines build and prepack scripts; no install lifecycle hook is present. Public source snippet (untrusted): ```json "scripts": { "build": "tsc -b", "clean": "rimraf lib tsconfig.tsbuildinfo", "lint": "oxlint --format stylish --config ../../oxlint.config.cjs src test --max-warnings 0", "prepack": "node -e \"const m=require('./package.json'),fs=require('node:fs');const missing=[m.main,...Object.values(m.bin||{})].filter(entry=>entry&&!fs.existsSync(entry));if(missing.length){console.error('prepack '+m.name+': not built ('+missing.join(', ')+' missing). Run the build before packing: a files entry that matches nothing is skipped silently, so the tarball would ship src only. ``` ### 3. Low: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 91.0% - **Path:** lib/index.js - **Public source:** [View source]() The package entrypoint exports a messenger channel. Public source snippet (untrusted): ```javascript __exportStar(require("./messenger-channel"), exports); //# sourceMappingURL=index.js.map ``` ### 4. Low: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 91.0% - **Path:** lib/node/data-server-connection.js - **Public source:** [View source]() The Node connection opens a socket using the supplied port and host, then relays it through the supplied channel. Public source snippet (untrusted): ```javascript const socket = net.createConnection({ port, host }); socket.once('error', reject); socket.once('connect', () => { // Drop the construction-time handler ``` ### 5. Low: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 91.0% - **Path:** lib/node/data-server-connection.js - **Public source:** [View source]() The Node connection opens a socket using the supplied port and host, then relays it through the supplied channel. Public source snippet (untrusted): ```javascript return (0, protocol_1.relayToPostMessageChannel)(channel, async () => openSocketTransport(await options.findPort()), { reportError: options.reportError }); } //# source ``` ### 6. Low: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 91.0% - **Path:** lib/browser/webview-data-port.js - **Public source:** [View source]() The browser port wraps the supplied channel in a JSON-RPC transport. Public source snippet (untrusted): ```javascript const transport = (0, protocol_1.createPostMessageTransport)(this.channel); const connection = (0, browser_1.createMessageConnection)(transport.reader, transport.writer ``` ## Dependencies and install lifecycle - **Lifecycle scripts present:** No - **Dependencies:** 0 - **Optional dependencies:** 0 - **Peer dependencies:** 5 - **Development dependencies:** 9 - **Published dependency-graph edges:** 5 ### Published dependency entries - @hydranium/protocol 1.0.0-next.333 (PeerDependency) - vscode-jsonrpc ^9.0.0 (PeerDependency) - vscode-messenger ^0.4.5 (PeerDependency) - vscode-messenger-common ^0.4.5 (PeerDependency) - vscode-messenger-webview ^0.4.5 (PeerDependency) ## Package metadata - **Package:** @hydranium/data-client-vscode - **Ecosystem:** npm - **Version:** 1.0.0-next.333 - **License:** MIT - **Version published:** 2026-10-25T16:13:12.215Z - **Package first seen:** 2026-10-14T23:37:35.865Z - **Package last seen:** 2026-11-04T11:53:08.876Z - **Known versions:** 68 - **Latest version:** 1.0.0-next.421 - **Appeal under review:** No - **Description:** VS Code client primitives for the hydranium data-server protocol head; companion of @hydranium/data-server.
