Security audit
nasal-language-basic
Security checks for vulnerabilities and agentic risk
Overview
This skill is a Nasal programming reference with relevant examples and no hidden installation or unrelated access instructions.
Use this as a programming reference. Module examples require your own trusted Nasal files; running property, timer, or listener examples affects the simulator. Both scanners reported no findings. SkillSpector coverage was partial, so the entire sole artifact and all reported gaps were manually reviewed; examples were not executed.
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
- 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
- Excessive AgencyUnrestricted Tool Access, Autonomous Decision Making, Scope Creep
