Security audit
Square
Security checks for vulnerabilities and agentic risk
Overview
This skill is a disclosed Square integration that can access and change Square business data, but it clearly scopes that power and requires user approval for sensitive actions.
Install only if you want an agent to administer Square through Maton. Use the least-privileged Square account and OAuth scopes, verify the connection ID before requests, approve writes only after checking the exact endpoint/resource/amount, and treat functions, triggers, and destinations as persistent automation that should be reviewed and removed when no longer needed.
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
