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 reviewed entry points and implementation match a Theia GLSP client’s stated purpose. Searches found no fetch, credential, environment, process execution or file read/write behavior; the observed storage and socket use are part of diagram session resumption and GLSP transport. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 94.0% - **Started:** 2026-10-29T18:29:59.440Z - **Finished:** 2026-10-29T18:30:35.094Z - **Download time:** 780 ms - **Static scan time:** 230 ms - **AI review time:** 34643 ms - **Total time:** 35654 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 package provides Theia and GLSP integration, including diagram UI, session resumption and socket forwarding. - **Trigger:** Importing the browser or node entry exposes integration classes; framework startup and diagram use invoke their normal behavior. - **Impact:** No unrelated data collection, credential handling, install-time contact or unrequested account action was found. - **Review source:** ai\_review - **Reviewed:** 2026-10-29T18:30:35.094Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The reviewed code exports integration modules, imports a loading stylesheet, stores resume state in sessionStorage and bridges the frontend channel to the configured GLSP server. - **Rationale:** The manifest has no install lifecycle hook, and the reviewed entry points and implementation match a Theia GLSP client’s stated purpose. Searches found no fetch, credential, environment, process execution or file read/write behavior; the observed storage and socket use are part of diagram session resumption and GLSP transport. - **Files touched:** src/browser/diagram-widget.ts, src/browser/window-session.ts, src/node/glsp-server-connection-handler.ts ### Review decision - **Verdict:** Clean - **Confidence:** 94.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The manifest exposes browser, node and root entry points; the root entry re-exports the browser surface., The scripts are build, clean, lint, prepack, test, typecheck and watch; there are no install lifecycle scripts., The diagram widget imports the package’s loading-overlay stylesheet for presentation., Window session handling stores random session identifiers in sessionStorage for diagram resume., The node connection handler bridges a frontend channel to a GLSP server socket, consistent with the package’s stated purpose. ## Affected versions and remediation This report applies to @hydranium/glsp-client-theia@1.0.0-next.373. - Review the evidence and your use of @hydranium/glsp-client-theia@1.0.0-next.373 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. High: Semantic Analysis Limited - **Category:** Scanner Coverage - **Confidence:** 100.0% - **Path:** style/diagram-loading.css - **Public source:** [View source]() A bounded semantic-analysis stage reached its safety limit; remaining detectors completed, but this package requires AI review. Public source snippet (untrusted): ```css stage = ast_semantic_analysis; reason = ast_parse_error; limitedFiles = 1 ``` ### 3. Low: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 94.0% - **Path:** package.json - **Public source:** [View source]() The manifest exposes browser, node and root entry points; the root entry re-exports the browser surface. Public source snippet (untrusted): ```json "sideEffects": [ "**/*.css" ], "main": "lib/index.js", "types": "lib/index.d.ts", "exports": { ".": { "types": "./lib/index.d.ts", "default": "./lib/index.js" }, "./browser": { "types": "./lib/browser/index.d.ts", ``` ### 4. Low: Suspicious Lifecycle Evidence - **Category:** Manifest - **Confidence:** 94.0% - **Path:** package.json - **Public source:** [View source]() The scripts are build, clean, lint, prepack, test, typecheck and watch; there are no install lifecycle scripts. Public source snippet (untrusted): ```json "test": "npm run typecheck:test && vitest run", "typecheck:test": "tsc --noEmit -p tsconfig.test.json && tsc --noEmit -p tsconfig.browser.test.json", "watch": "tsc -b tsconfig.browser.json -w --preserveWatchOutput" }, "devDependencies": { " ``` ### 5. Low: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 94.0% - **Path:** src/browser/diagram-widget.ts - **Public source:** [View source]() The diagram widget imports the package’s loading-overlay stylesheet for presentation. Public source snippet (untrusted): ```typescript // Shipped by this package rather than left to adopters: an overlay whose // stylesheet was forgotten is an unstyled div in normal flow, which is a silent // failure. Adopters override individual rules from their own stylesheet. import '../../style/diagram-loading.css'; /** Class on the overlay root. Adopters style / override via this contract. */ export const DIAGRAM_LOADING_CLASS = 'h ``` ### 6. Low: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 94.0% - **Path:** src/browser/window-session.ts - **Public source:** [View source]() Window session handling stores random session identifiers in sessionStorage for diagram resume. Public source snippet (untrusted): ```typescript protected claim(): WindowSession { const created: WindowSession = { id: randomUuid(), resumeToken: randomUuid() }; try { const storage = globalThis.sessionStorage; const stored = this.parse(storage.getItem(WINDOW_SESSION_KEY)); const session = stored && storage.getItem(RELEASED_WINDOW_SESSION_KEY) === stored.id ? stored : created; storage.setItem(WINDOW_SESSION_KEY, JSON.stringify(session)); storage.removeItem(RELEASED_WINDOW_SESSION_KEY); globalThis.addEventListener?.('pagehi ``` ### 7. Low: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 94.0% - **Path:** src/node/glsp-server-connection-handler.ts - **Public source:** [View source]() The node connection handler bridges a frontend channel to a GLSP server socket, consistent with the package’s stated purpose. Public source snippet (untrusted): ```typescript /** * Bridges a Theia browser-frontend channel to a GLSP server's TCP socket. * * The port discovery, the buffer-and-replay race fix, the connect orchestration * and the byte forwarder live on the cross-head * {@link [redacted]} base; this subclass supplies * only the GLSP specifics — the per-language servicePath * (`GLSPContribution.servicePath + '/' + languageContributionId`), the port * command, the log labels.
