Spotify

• Outcome: Review
• Latest audit: Nov 4, 2026 · 5:58 AM UTC
• Version: 1.0.6

Overview

Spotify actions have clear approval controls, but setup executes unverified remote code and leaves broader agent changes unexplained.

Review and approve the CLI installation separately, including any changes to other agents' skills. Prefer a verified release and disable unwanted skill synchronization. OOMOL will mediate Spotify access; retain the skill's approval requirements for account changes. The remote installer contents remain unverified, although no malicious behavior was established in the bundled artifact.

A.I.G

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: 98% confidence

Finding

The visible behavior is remote installer execution rather than Spotify data management. Although installation can be a supporting implementation detail, this chunk provides no evidence that the Oomol installer supports Spotify functionality. The downloaded script's contents and any further effects are not visible.

External Script Fetching

High

• Category: Supply Chain
• Confidence: 98% confidence

Finding

The setup instructions pipe a mutable remote script directly into Bash without pinning its contents or verifying integrity; the PowerShell alternative has the same execution pattern. Compromise of the distribution endpoint could execute attacker-controlled code with the agent's local permissions, exposing accessible files or credentials. Restricting installation to a missing-CLI error reduces exposure but does not mitigate the supply-chain risk when installation occurs.

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.
