Sendly: Building Onboarding Workflows
Security checks for vulnerabilities and agentic risk
Overview
This skill is a clearly scoped Sendly workflow helper that requires user confirmation before live or destructive email automation changes.
Install only if you intend to let the agent inspect and manage Sendly workflows. Review proposed triggers, email steps, templates, and workflow names carefully before giving explicit approval, especially before enabling, editing, or deleting a workflow because those changes can affect real contacts.
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
