Security audit

Stormboard

Security checks for vulnerabilities and agentic risk

Overview

The Stormboard read actions fit the purpose, but setup can execute unverified remote software without a user approval step.

Review and approve the oo installation separately before using this skill. Its installer was not verified, and the dependency may install additional agent skills. Review its startup synchronization controls and ensure you accept OOMOL handling your Stormboard connection and requests.

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
Vulnerability Patterns
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration

  • Excessive AgencyUnrestricted Tool Access, Autonomous Decision Making, Scope Creep

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
98% confidence
Finding

The supplied command installs software by piping a remotely fetched script into Bash; it does not search or read Stormboard data. No evidence in the chunk establishes this installation as a supporting dependency for the declared Stormboard functionality. The downloaded script's additional behavior cannot be determined from the supplied code.

External Script Fetching

High
Category
Supply Chain
Confidence
98% confidence
Finding

Piping a downloaded script directly into Bash executes mutable remote content with the invoking user's privileges, without an integrity check or review step. Compromise of the installation endpoint or its delivery infrastructure could therefore lead to local code execution; the PowerShell equivalent has the same risk, despite the legitimate setup purpose.

Fallback setup executes downloaded installation scripts without warning the user about system changes or remote-code execution.

Medium
Category
Output Handling
Confidence
96% confidence
Finding

When the CLI is missing, the skill directs the agent to install software by executing a remote script without first obtaining approval for local code execution and system changes. Restricting this to first-time setup reduces exposure, but a request to read Stormboard data does not itself authorize installing software.

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.

External Transmission

Medium
Category
Data Exfiltration
Confidence
50% confidence
Finding

Data is being sent to an external URL. This could be legitimate telemetry or data exfiltration. Manual review is recommended.
