This is a real unresolved security risk rather than confirmed malicious intent. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 86.0% - **Started:** 2026-07-01T10:36:19.689Z - **Finished:** 2026-07-01T10:37:50.918Z - **Download time:** 758 ms - **Static scan time:** 110 ms - **AI review time:** 90360 ms - **Total time:** 91229 ms ## Security analysis ### Published attack-surface review - **Summary:** No install-time malware was found, but the user-invoked dashboard exposes an unauthenticated local web API that can write agent skill files. This is a real unresolved security risk rather than confirmed malicious intent. - **Trigger:** User runs \`spark dashboard\` or \`spark ui\` - **Impact:** A local web page or reachable network client could create or potentially path-traverse skill files in the project, influencing later AI-agent behavior. - **Evidence paths:** package.json, bin/spark.js, src/cli/index.js, src/cli/install.js, bin/spark-install.sh, src/dashboard/server.js, skills/brainstorming/scripts/server.cjs, .opencode/plugins/spark.js - **Review source:** ai\_review - **Reviewed:** 2026-07-01T10:37:50.918Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** unauthenticated CORS-enabled local dashboard writes user-controlled skill content - **Attack narrative:** If a user starts the dashboard, src/dashboard/server.js listens on port 4321 with permissive CORS and no authorization. Its POST /api/skills route accepts arbitrary name/content and writes SKILL.md under a path derived from that name, creating a route for cross-origin or network-triggered AI-agent skill planting/path traversal. This requires explicit dashboard launch and is not install-time execution. - **Rationale:** Static source inspection does not show lifecycle execution, credential theft, exfiltration, or staged payloads, so a malicious block is not justified. The dashboard write API is nevertheless a concrete critical vulnerability affecting AI-agent control surfaces, so warn/suspicious is appropriate. - **Files touched:** .agent/skills/\/SKILL.md, .spark-lock.json, agent config skill/plugin/hook paths during explicit install - **Network endpoints:** http://localhost:4321, https://fonts.googleapis.com, https://cdn.jsdelivr.net, https://unpkg.com ### Review decision - **Verdict:** Suspicious - **Confidence:** 86.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Critical Vulnerability - **False-positive risk:** Medium - **Evidence for:** src/dashboard/server.js starts an HTTP dashboard on port 4321 without an auth check, src/dashboard/server.js sets Access-Control-Allow-Origin:\* and POST /api/skills writes user-supplied content, src/dashboard/server.js builds .agent/skills path from unsanitized data.name, allowing path traversal risk, src/dashboard/server.js auto-opens http://localhost:4321 via child\_process exec on dashboard start - **Evidence against:** package.json defines no install/preinstall/postinstall lifecycle scripts, bin/spark.js only dispatches explicit CLI commands; install runs only when user invokes spark install, bin/spark-install.sh installs local agent skills/hooks by symlink/copy and writes .spark-lock.json; no network fetch or exfiltration seen, skills/brainstorming/scripts/server.cjs binds to 127.0.0.1 by default and uses a per-session token for HTTP/WebSocket access, OpenCode plugin injects bundled using-spark guidance and registers local skills path; no credential harvesting seen ## Public findings ### 1.
