file-transfer-thru-local-workspace
Local file upload/download service with skill browser for OpenClaw
Skill provides legitimate file transfer functionality but exhibits undisclosed credential harvesting behavior and hardcoded path vulnerability that exposes sensitive configuration data.

⚠
Use with caution
Review and sanitize the credential extraction logic. Remove hardcoded paths. Document why openclaw.json is accessed and clarify skill download security implications.

Findings 4 items

Severity Finding Location
High
Undeclared credential file access Credential Theft
Both install.sh and upload-server.js read ~/.openclaw/openclaw.json to extract authentication tokens. This credential harvesting is not declared in SKILL.md or documented as a capability.
GATEWAY_TOKEN=$(grep -o '"token": *"[^"]*"' "${CONFIG_FILE}" ...)
→ Document why openclaw.json is accessed. Consider using a service account instead of gateway credentials.
 install.sh:44
High
Hardcoded user path creates information disclosure Sensitive Access
upload-server.js has a hardcoded path '/home/admin/.openclaw/' that bypasses the HOME environment variable. This can cause the skill to read the wrong user's configuration file if HOME is unset or different.
const configPath = path.join(process.env.HOME || '/home/admin', '.openclaw/openclaw.json');
→ Remove hardcoded path. Only use process.env.HOME and fail gracefully if not set.
 src/upload-server.js:31
Medium
Skill download exposes other skills' secrets Priv Escalation
The skill can enumerate and package all installed skill packages. Many skills contain API keys or credentials in their configs. Downloading all skills provides a credential aggregation attack vector.
const zip = spawn('zip', ['-r', zipPath, skillName, '-x', '*/node_modules/*'], ...)
→ Implement permission checks for skill download. Warn users about credential exposure in skill packages.
 src/upload-server.js:200
Medium
Permissions mismatch between declared and actual Doc Mismatch
package.json declares 'filesystem: [write:workspace, read:skills]' but the skill actually reads openclaw.json (credential file) which is outside declared scope.
"filesystem": ["write:workspace", "read:skills"]
→ Update permissions to include 'read:config' or 'read:credentials' if accessing openclaw.json is intentional.

Security Positives

✓ Token authentication protects the upload/download endpoints
✓ Path traversal protection using path.basename()
✓ Independent uploads/ directory isolates user files
✓ Systemd service creation provides proper Linux integration
✓ CORS headers configured for browser security
