Security audit

Runscope

Security checks for vulnerabilities and agentic risk

Overview

The Runscope read operations are appropriately scoped, but automatic software setup needs review because it executes unverified remote code and can introduce persistent agent changes.

Review and approve the CLI installation separately, using a verified release. Understand that OOMOL handles the Runscope connection and credentials. Review the CLI's persistent skill synchronization; its documentation provides OO_SKILLS_SYNC_DISABLED to disable startup synchronization. The full bundled artifact was inspected, but the remote installer and hosted connector implementation remain unverified. No malicious behavior was established.

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
99% confidence
Finding

The supplied command executes an external installation script from cli.oomol.com. Nothing in the chunk connects this installer to Runscope or implements Runscope data access. Executing an unrelated remote installer is a materially different capability from the declared search-and-read purpose. The downloaded script's specific actions cannot be determined from this chunk.

External Script Fetching

High
Category
Supply Chain
Confidence
99% confidence
Finding

The command pipes a remotely fetched, mutable script directly into Bash without verifying its integrity or reviewing its contents; the PowerShell alternative has the same execution pattern. A compromised distribution endpoint or installer could execute arbitrary code with the agent process's permissions, potentially accessing local secrets or modifying files. HTTPS and the legitimate dependency context reduce suspicion of malicious intent but do not establish installer integrity.

Automatic setup executes a remotely downloaded installer without warning about system changes.

Medium
Category
Output Handling
Confidence
96% confidence
Finding

When the CLI is missing, the skill directs the agent to install software without requiring approval or explaining the resulting local system changes. A request to read Runscope data does not inherently authorize installing executable software, although limiting installation to a missing-command error reduces unnecessary exposure.

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.
