Viggle

• Outcome: Review
• Latest audit: Nov 3, 2026 · 11:17 AM UTC
• Version: 1.0.4

Overview

Viggle operations have clear approval controls, but setup can run an unverified remote installer without separate user approval.

Review and install a verified CLI release yourself before use, and check its automatic skill synchronization settings. OOMOL will mediate your connected Viggle account and requests. The bundled instructions protect writes and deletions with confirmation, but the remote installer and exact runtime release could not be verified.

Vulnerability Patterns

• Skill Instruction Hijacking: Alters the agent's session goals or safety constraints when the skill loads
• Agent Memory Poisoning: Writes attacker-controlled rules into memory that affect later sessions
• Remote Payload Retrieval and Execution: Fetches external code whose behavior can change after review
• Embedded Malicious Code: Ships malicious scripts inside the skill and executes them locally
• Unauthorized Access and Privilege Escalation: Obtains permissions beyond the task's legitimate needs

Vulnerability Patterns

• Supply Chain: Unpinned Dependencies, External Script Fetching, Obfuscated Code
• Excessive Agency: Unrestricted Tool Access, Autonomous Decision Making, Scope Creep
• MCP Tool Poisoning: Hidden Instructions, Unicode Deception, Parameter Description Injection
• Prompt Injection: Instruction Override, Hidden Instructions, Exfiltration Commands
• Data Exfiltration: External Transmission, Env Variable Harvesting, File System Enumeration

Findings (3)

Description-Behavior Mismatch

High

• Category: MCP Tool Poisoning
• Confidence: 97% confidence

Finding

The supplied code installs software from an Oomol-hosted endpoint; it does not demonstrate any Viggle data operations. Although dependency installation can be a supporting implementation detail, the supplied content establishes no connection between this installer and the declared Viggle functionality. The remote 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: 97% confidence

Finding

The command executes a mutable remote script immediately without verifying a pinned version, signature, or trusted digest; the PowerShell alternative has the same issue. A compromised distribution endpoint could execute arbitrary code with the agent process's permissions, potentially exposing local files or credentials. Conditional setup and the declared Bash(oo *) tool restriction reduce exposure, but do not establish that execution would be blocked in every host environment.

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.
