ProjectManager

Security checks for vulnerabilities and agentic risk

Overview

The ProjectManager reads are appropriately scoped, but setup can run an unverified installer whose broader effects on agent skills are not explained.

Review setup before installing. Prefer a verified, preinstalled CLI and explicitly approve any software installation. Check its automatic skill synchronization; the publisher documents OO_SKILLS_SYNC_DISABLED as a control in the [command reference](https://github.com/oomol-lab/oo-cli/blob/main/docs/commands.md). Connect only the ProjectManager permissions you need and understand OOMOL's credential handling and billing. Remote installer behavior remains unverified.

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

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
99% confidence
Finding

The supplied command performs remote script execution for an Oomol CLI installer rather than searching or reading ProjectManager data. Nothing in the supplied chunk establishes this installation as a supporting dependency for ProjectManager access. The downloaded script's contents and further effects are not visible.

External Script Fetching

High
Category
Supply Chain
Confidence
98% confidence
Finding

Piping a mutable remote script directly into Bash executes its contents without prior inspection or independent integrity verification; the PowerShell alternative has the same weakness. If the installer distribution infrastructure is compromised, this can execute attacker-controlled code with the agent's local permissions, exposing accessible files and credentials. HTTPS and the legitimate CLI dependency reduce some concerns but do not eliminate this supply-chain risk.

The setup workflow executes remote installer scripts without warning about system-level effects.

Medium
Category
Output Handling
Confidence
93% confidence
Finding

The setup instructions direct the agent to execute remote installers when the CLI is missing, without explaining their local effects or requiring installation-specific approval. Although this is a legitimate dependency and a conditional fallback, it expands a data-reading task into local software installation with the agent's operating-system permissions.

Autonomous Decision Making

Medium
Category
Excessive Agency
Confidence
80% confidence
Finding

Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.
