SurfAgent Gmail
Security checks for vulnerabilities and agentic risk
Overview
This Gmail skill is a disclosed automation guide for reading, composing, replying to, and verifying Gmail tasks, with no bundled executable code or hidden persistence.
Install only if you intend to let an agent operate Gmail through SurfAgent/browser tools. Review email drafts before sending when the task is sensitive, and grant Gmail session access only in an account context you are comfortable automating.
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
