PontoFato
Security checks for vulnerabilities and agentic risk
Overview
This skill is a straightforward PontoFato API/MCP helper for Brazilian address and company lookups, with payment and token handling disclosed and bounded.
Before installing, understand that lookups go to pontofato.com and may reveal the CEP, coordinates, or company identifier you ask about. Paid calls should only happen after you approve the quoted item and amount, and any cred_ or mmk_ tokens should be treated as secrets.
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
