Sendly: Reviewing Email Performance
Security checks for vulnerabilities and agentic risk
Overview
This skill is a read-only Sendly email analytics helper with clear limits and no bundled executable behavior.
Install this only if you want the agent to read Sendly analytics, campaign stats, usage counters, and bounced-email details. It is designed as read-only, but the reports may include recipient addresses and delivery history, so use it in workspaces where that email-performance data is appropriate to expose to the agent.
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
