Resource Flow (Hub Planner)

• Outcome: Review
• Latest audit: Nov 3, 2026 · 10:59 AM UTC
• Version: 1.0.4

Overview

This integration needs review because setup executes downloaded code and its dependency can also change installed agent skills.

Review and verify the CLI separately before allowing setup. Its broader skill synchronization is not explained here; the publisher documents OO_SKILLS_SYNC_DISABLED=1 to prevent startup writes to agent skill directories in the [command reference](https://github.com/oomol-lab/oo-cli/blob/main/docs/commands.md). Connect only the intended Hub Planner account and approve each creation or invitation. The complete bundled file was inspected, but remote installers and hosted connector behavior remain unverified.

A.I.G

Vulnerability Patterns

• Skill Instruction Hijacking: Alters the agent's session goals or safety constraints when the skill loads
• Agent Memory Poisoning: Writes attacker-controlled rules into memory that affect later sessions
• Remote Payload Retrieval and Execution: Fetches external code whose behavior can change after review
• Embedded Malicious Code: Ships malicious scripts inside the skill and executes them locally
• Unauthorized Access and Privilege Escalation: Obtains permissions beyond the task's legitimate needs

Vulnerability Patterns

• Supply Chain: Unpinned Dependencies, External Script Fetching, Obfuscated Code
• Excessive Agency: Unrestricted Tool Access, Autonomous Decision Making, Scope Creep
• MCP Tool Poisoning: Hidden Instructions, Unicode Deception, Parameter Description Injection
• Prompt Injection: Instruction Override, Hidden Instructions, Exfiltration Commands
• Data Exfiltration: External Transmission, Env Variable Harvesting, File System Enumeration

Findings (3)

Description-Behavior Mismatch

High

• Category: MCP Tool Poisoning
• Confidence: 98% confidence

Finding

The supplied code performs third-party software installation rather than Resource Flow data operations. Nothing in the chunk establishes this installation as a supporting dependency for the declared integration. The downloaded script's contents are not provided, so its further behavior cannot be determined.

Content

No source excerpt is available for this finding.

External Script Fetching

High

• Category: Supply Chain
• Confidence: 96% confidence

Finding

The installation command executes a mutable remote script without a pinned version or independent integrity verification; the PowerShell alternative has the same weakness. Compromise of the distribution endpoint could execute attacker-controlled code with the agent's local permissions, potentially exposing files and credentials; the missing-CLI prerequisite limits exposure but does not remove the risk.

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.
