Security audit

Canva

Security checks for vulnerabilities and agentic risk

Overview

The skill is mostly coherent for operating Canva through OOMOL, but its first-time setup tells agents to run remote installer scripts directly in a shell without pinning or verification.

Install only if you are comfortable using OOMOL as the Canva connector and reviewing write actions before approval. Avoid running the provided curl-to-bash or irm-to-iex installer commands blindly; use a verified install path, review the installer, and confirm the CLI source first.

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

External Script Fetching

Finding

The skill instructs users to install software by piping a remotely fetched script directly into a shell (curl ... | bash), which is a classic supply-chain and remote code execution risk. If the hosting domain, network path, or install script is compromised, arbitrary code would execute immediately on the user's machine with the user's privileges.

Finding

The manifest description uses sweeping activation language that appears to cover all Canva-related tasks, including loosely related requests, without narrowing conditions or exclusions. This creates ambiguity about when the skill should activate versus when a normal response or another tool would be more appropriate.
