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 declares no install lifecycle hooks, and the reviewed entry points expose Theia/GLSP integration code. Searches found no credential handling, unrelated network endpoints, or process execution; the flagged CSS is ordinary UI styling. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 95.0% - **Started:** 2026-10-29T18:28:52.161Z - **Finished:** 2026-10-29T18:29:22.816Z - **Download time:** 520 ms - **Static scan time:** 213 ms - **AI review time:** 29921 ms - **Total time:** 30655 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; inspected behavior supports GLSP-on-Theia diagram clients. - **Trigger:** Package import exposes browser or Node framework classes; frontend startup claims a diagram session, and client operation opens its configured GLSP connection. - **Impact:** No unauthorized data collection, unrelated network contact, or harmful account action was identified. - **Review source:** ai\_review - **Reviewed:** 2026-10-29T18:29:22.816Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The package exports Theia/GLSP integration code, stores resume identifiers in sessionStorage, and bridges a frontend channel to a GLSP server TCP socket. - **Rationale:** The manifest declares no install lifecycle hooks, and the reviewed entry points expose Theia/GLSP integration code. Searches found no credential handling, unrelated network endpoints, or process execution; the flagged CSS is ordinary UI styling. - **Files touched:** src/browser/window-session.ts ### Review decision - **Verdict:** Clean - **Confidence:** 95.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The manifest has no install, preinstall, or postinstall hook; its scripts cover build, cleanup, lint, prepack, tests, and watch., The root entry re-exports the browser-facing package surface., The Node connection handler bridges a Theia frontend channel to a GLSP server TCP socket, consistent with the package’s stated purpose., The window session service stores diagram resume identifiers in sessionStorage., The flagged CSS defines a themed diagram-loading overlay and spinner. - **Evidence against:** The package includes TCP connection and automatic client-restart capabilities, but the inspected code ties them to GLSP client operation., The session service creates and stores resume tokens automatically when the frontend starts, but uses them for diagram session resumption. ## Affected versions and remediation This report applies to @hydranium/glsp-client-theia@1.0.0-next.367. - Review the evidence and your use of @hydranium/glsp-client-theia@1.0.0-next.367 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: Suspicious Lifecycle Evidence - **Category:** Manifest - **Confidence:** 95.0% - **Path:** package.json - **Public source:** [View source]() The manifest has no install, preinstall, or postinstall hook; its scripts cover build, cleanup, lint, prepack, tests, and watch.

Low: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 95.0% - **Path:** lib/index.js - **Public source:** [View source]() The root entry re-exports the browser-facing package surface. Public source snippet (untrusted): ```javascript // Root barrel re-exports the browser-side surface, mirroring the root entry of // the package this one integrates: `@eclipse-glsp/theia-integration`'s own // `main` is its browser tier, so an adopter importing the bare specifier // expects the same surface he ``` ### 5. Low: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 95.0% - **Path:** src/node/glsp-server-connection-handler.ts - **Public source:** [View source]() The Node connection handler bridges a Theia frontend channel to a GLSP server TCP 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.serv ``` ### 6. Low: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 95.0% - **Path:** src/browser/window-session.ts - **Public source:** [View source]() The window session service stores diagram resume identifiers in sessionStorage.

Low: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 95.0% - **Path:** style/diagram-loading.css - **Public source:** [View source]() The flagged CSS defines a themed diagram-loading overlay and spinner. Public source snippet (untrusted): ```text /* Loading overlay shown by HydraniumGlspDiagramWidget until the diagram load settles. Imported by the widget module itself, so an adopter cannot forget it; every rule is overridable from an adopter stylesheet loaded afterwards.
