Security audit
xero
Security checks for vulnerabilities and agentic risk
Overview
This skill provides a disclosed Xero accounting integration through Maton, with sensitive financial and automation abilities gated by explicit approval and least-privilege guidance.
Install only if you intend to let Maton access your Xero accounting data. Prefer OAuth, choose the narrowest Xero scopes available, confirm every write or automation setup, and be especially careful with hosted functions, trigger destinations, or raw API-key use because they can create ongoing data access or forwarding.
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
