SurveyMethods

Security checks for vulnerabilities and agentic risk

Overview

The SurveyMethods workflow is coherent, but its automatic setup can execute unverified remote software and make broader agent changes without clear user control.

Review and approve CLI installation separately, including its bundled-skill synchronization, before allowing setup. Use a verified release and retain confirmation for SurveyMethods changes. OOMOL mediates access to your account data. The complete bundled artifact was inspected, but the external installers and live connector implementation were not verified; no malicious payload 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

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
97% confidence
Finding

The supplied command performs remote software installation, not SurveyMethods data operations. Although dependency installation can be a supporting implementation detail, this chunk establishes no connection between the Oomol installer and SurveyMethods. The downloaded script's contents and further effects are not available for assessment.

Content

No source excerpt is available for this finding.

External Script Fetching

High
Category
Supply Chain
Confidence
98% confidence
Finding

The command executes mutable remote content directly in Bash without verifying a pinned version, signature, or independently trusted digest; the PowerShell alternative has the same issue. Compromise of the installer distribution could yield arbitrary code execution with the agent's local privileges, although this fallback is conditional and there is no evidence the installer is currently malicious.

Content

The setup workflow instructs the agent to execute downloaded installer scripts without warning about the system-level effects.

Medium
Category
Output Handling
Confidence
92% confidence
Finding

The missing-CLI fallback instructs installation of external software without first obtaining approval for local system changes or explaining their scope. This extends authorization for SurveyMethods operations into host modification, although the conditional trigger and declared tool restrictions may limit execution.

No source excerpt is available for this finding.

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.
