Security audit
hemnet-fpx
Security checks for vulnerabilities and agentic risk
Overview
The skill coherently retrieves public property listings, with disclosed browser pairing and no harmful behavior found in its bundled instructions.
Approve only hemnet.se and fetch access, verify the extension release checksum, and revoke pairing when finished. Hemnet login is unnecessary; a separate browser profile can avoid carrying an existing account session. The CLI and extension are external software whose installed versions were not audited here.
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
