Security audit
halftone-art
Security checks for vulnerabilities and agentic risk
Overview
This halftone art toolkit fits its stated purpose, with minor precautions for local previews and externally hosted fonts.
Preview only a dedicated asset folder using python3 -m http.server 8000 --bind 127.0.0.1 --directory <preview-folder>, and stop it afterward. Use system or self-hosted fonts if you want to avoid Google requests. All ten bundled files were inspected, including the scanner's partial-coverage files; browser and network behavior were not exercised.
Vulnerability Patterns
- Skill Instruction HijackingAlters the agent's session goals or safety constraints when the skill loads
- Agent Memory PoisoningWrites attacker-controlled rules into memory that affect later sessions
- Remote Payload Retrieval and ExecutionFetches external code whose behavior can change after review
- Embedded Malicious CodeShips malicious scripts inside the skill and executes them locally
- Unauthorized Access and Privilege EscalationObtains permissions beyond the task's legitimate needs
Vulnerability Patterns
- Output HandlingUnvalidated Output Injection, Cross-Context Output, Unbounded Output
- Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
- Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
- Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
- Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code

- Finding
python3 -m http.server 8000binds to all network interfaces by default and serves the current directory without authentication. Although HTTP preview is appropriate for this canvas workflow and the instructions suggest a dedicated folder, other reachable hosts could retrieve source photos or any additional files placed in the served directory.- Content

- Finding
npx commands without a version suffix (e.g. @1.0.0) create a rug-pull risk if the upstream server is compromised and publishes a malicious update.

Opening the page initiates connections and font requests to Google, exposing the visitor's IP address and request metadata. The template's usage instructions do not disclose this external dependency or its privacy implications.
