Security audit

Raygun

Security checks for vulnerabilities and agentic risk

Overview

The Raygun workflow includes clear safeguards, but its setup directs the agent to execute downloaded installation code without a separate review or approval step.

Review and approve a verified oo CLI installation separately before using the skill. Raygun requests pass through OOMOL, and changes or deletion should retain the stated approval requirements. The downloaded installer and installed CLI were not verified in this review.

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

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
97% confidence
Finding

The supplied code performs remote script installation rather than any visible Raygun operation. Nothing in the chunk establishes that this installer is a supporting dependency for Raygun. The downloaded script's contents are not supplied, so its further effects cannot be determined.

Content

No source excerpt is available for this finding.

Credential Access

High
Category
Privilege Escalation
Confidence
70% confidence
Finding

Code accesses credential files (SSH keys, AWS credentials, etc.). This could indicate credential theft attempts.

External Script Fetching

High
Category
Supply Chain
Confidence
98% confidence
Finding

Piping a remotely fetched, unpinned script directly into Bash executes its contents with the invoking account's permissions without prior integrity verification or review. HTTPS and the legitimate OOMOL dependency reduce some risks but do not protect against a compromised distribution endpoint or altered installer; the PowerShell alternative has the same execution pattern.

The fallback setup instructs the agent to execute downloaded installation scripts without warning the user about local system changes or obtaining approval.

Medium
Category
Output Handling
Confidence
95% confidence
Finding

The fallback directs an agent to install software on the local system after a missing-command error without requiring informed user approval. Although conditional and relevant to the workflow, installation crosses a different authorization boundary from performing a Raygun action and may modify executables, configuration, or shell startup files.

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.
