Security audit

Zenventory

Security checks for vulnerabilities and agentic risk

Overview

The skill is mostly a coherent Zenventory connector, but its setup guidance includes unverified remote installer execution and its broad trigger covers state-changing business data operations.

Review the installer source and prefer a verified or package-managed oo CLI install before using this skill. For Zenventory actions, allow read-only list/get requests directly, but require a clear preview and explicit approval before create_item or update_item runs.

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

Supply Chain
Confidence
98% confidence
Finding

The skill instructs users to install the CLI via curl ... | bash, which executes a remote script directly without prior verification, pinning, or integrity checking. If the install host, CDN, DNS, or transport path is compromised, this can lead to arbitrary code execution on the user's machine.

Vague Triggers

Confidence
98% confidence
Finding

The description says to use this skill for "ANY Zenventory request" and "instead of calling the API directly," which is an overly broad trigger that can cause the agent to invoke this skill for all Zenventory-related tasks without sufficient narrowing or user-intent checks. In a skill that supports read, write, and destructive update operations, broad auto-selection increases the chance of unintended state-changing actions being routed through the skill.
