Brevo Automation

Security checks for vulnerabilities and agentic risk

Overview

This Brevo automation skill is coherent and purpose-aligned, but users should be careful with its ability to update campaigns and delete inactive templates.

Install only if you intend to let the agent manage Brevo marketing assets through Rube MCP. Before allowing updates or deletions, especially template deletion, verify the exact campaign or template ID/name and confirm the action yourself.

A.I.G

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

Finding

The skill explicitly includes a template deletion workflow but provides no instruction to require explicit user confirmation before performing the destructive action. In an agentic context, this increases the risk of accidental or overly broad deletion of inactive email templates, which can disrupt marketing operations and remove reusable assets without a clear recovery path.
