redfin-fpx
Security checks for vulnerabilities and agentic risk
Overview
This is a disclosed guide for read-only Redfin queries through fpx; its persistent browser pairing and signed-in Redfin access are clearly described and scoped to the stated purpose.
Install only if you trust @fetchproxy/cli and the Transporter extension. Keep the fpx profile scoped to redfin.com, and remember that saved homes and saved searches can reveal private real-estate activity from your signed-in Redfin account in shell output.
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
