The issue is best treated as a vulnerability/dual-use risk rather than malware. - **Trigger:** User runs \`spark dashboard\` or \`spark ui\`. - **Impact:** A reachable webpage or network client could write a project skill file, potentially escaping the intended skills directory via path traversal. - **Evidence paths:** package.json, bin/spark.js, src/cli/index.js, src/cli/install.js, bin/spark-install.sh, src/dashboard/server.js, .opencode/plugins/spark.js, skills/brainstorming/scripts/server.cjs - **Review source:** ai\_review - **Reviewed:** 2026-07-01T12:18:43.777Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** CORS-enabled dashboard POST writes arbitrary skill content using an unsanitized path component. - **Attack narrative:** The package is primarily an agent skills/plugin distribution. A user-invoked dashboard command starts a CORS-permissive HTTP server and lets POST /api/skills write supplied content under a path derived from unsanitized data.name; because the server does not pin listen() to loopback, this creates a real write-surface if the dashboard is reachable. I did not find install-time execution, credential collection, or exfiltration that would support a malicious verdict. - **Rationale:** Static inspection supports a suspicious warning for a dashboard write vulnerability, not a publish block for malware. The scanner's dangerous-delta hint maps to package-aligned dashboard code, but that code still exposes an unresolved arbitrary skill write risk. - **Files touched:** .agents/skills/\/SKILL.md, .spark-lock.json, agent config skill/hook/plugin paths during user-invoked install - **Network endpoints:** http://localhost:4321, https://fonts.googleapis.com, https://cdn.jsdelivr.net, https://cdnjs.cloudflare.com ### Review decision - **Verdict:** Suspicious - **Confidence:** 78.0% - **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 with Access-Control-Allow-Origin: \*., src/dashboard/server.js POST /api/skills writes data.content to path.join(process.cwd(), '.agents/skills', data.name, 'SKILL.md') without sanitizing data.name., src/dashboard/server.js listen(PORT) omits a loopback host, so the dashboard may bind beyond localhost., src/dashboard/server.js auto-opens http://localhost:4321 via child\_process exec when dashboard is run. - **Evidence against:** package.json has no install/preinstall/postinstall lifecycle hooks., bin/spark.js only dispatches user-invoked CLI commands., bin/spark-install.sh installs skills/hooks for detected coding agents only when spark install is run., .opencode/plugins/spark.js injects bundled using-spark instructions and registers bundled skills, matching package purpose., skills/brainstorming/scripts/server.cjs uses loopback by default, per-session token auth, and path checks for served files., No credential harvesting, remote exfiltration endpoint, persistence outside install flow, or destructive behavior found. ## Public findings ### 1.
