Security checks for vulnerabilities and agentic risk
Overview
This skill is a disclosed Google Sheets integration that uses Maton OAuth/CLI access and includes appropriate cautions for writes, credentials, hosted functions, and persistent triggers.
Install only if you are comfortable authorizing Maton to access the Google Sheets account you choose. Confirm every write, connection, function deployment, trigger, and destination explicitly, prefer read-only scopes when possible, and avoid API-key fallback unless the CLI cannot be used.
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
