SurveyMonkey

Security checks for vulnerabilities and agentic risk

Overview

The SurveyMonkey workflow is scoped, but its setup executes unverified remote code and its CLI can silently install additional agent skills.

Review and verify a specific CLI release before allowing setup. Disable startup skill synchronization with OO_SKILLS_SYNC_DISABLED=1 unless you want additional skills installed across your agents. Connect only the intended SurveyMonkey account, consider OOMOL's access to sensitive survey data, and retain the required confirmation before writes. The downloaded installers and exact installed release remain outside the inspected artifact.

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
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code
  • Excessive AgencyUnrestricted Tool Access, Autonomous Decision Making, Scope Creep
  • MCP Tool PoisoningHidden Instructions, Unicode Deception, Parameter Description Injection
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
97% confidence
Finding

The supplied chunk performs remote installer execution rather than SurveyMonkey operations. Although dependency installation can be a supporting implementation detail, this chunk establishes no relationship between the Oomol installer and the declared SurveyMonkey functionality. The downloaded script is not supplied, so its further behavior cannot be determined.

External Script Fetching

High
Category
Supply Chain
Confidence
97% confidence
Finding

The fallback installation command downloads a mutable remote script and executes it immediately without version pinning, integrity verification, or inspection; the PowerShell alternative uses the same unsafe pattern. Although installation is conditional and the domain belongs to the stated CLI provider, compromise of the distribution endpoint could execute attacker-controlled code with the invoking user's privileges, exposing accessible files and credentials.

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.

- **`OOMOL_INSUFFICIENT_CREDIT`** — OOMOL billing stop. Recharge at `https://console.oomol.com/billing/token-recharge` before retrying.

- **HTTP 402 without `OOMOL_INSUFFICIENT_CREDIT`** — the third-party account itself has no active plan or credit. Report the provider error message as is; do not ask the user to recharge OOMOL.

External Transmission

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.
