Simple Analytics

Security checks for vulnerabilities and agentic risk

Overview

The analytics workflow is coherent, but its setup directs the agent to run unverified downloaded software without asking you first.

Review and approve CLI installation separately before allowing the setup fallback. Check the downloaded installer and the CLI's automatic skill-installation behavior; the remote installer contents remain unverified. Connecting Simple Analytics authorizes OOMOL to mediate account access. Retain the skill's explicit confirmation requirements for writes.

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

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
99% confidence
Finding

The supplied command executes an installer hosted by Oomol, not Simple Analytics. Nothing in the provided chunk establishes that this installation supports the declared analytics functionality. The remote script's contents are not provided, so its additional behavior cannot be assessed.

External Script Fetching

High
Category
Supply Chain
Confidence
98% confidence
Finding

The command pipes a mutable HTTPS response directly into Bash without version pinning or independent integrity verification. Compromise of the installer distribution path could execute attacker-controlled code with the invoking user's permissions, exposing local files and credentials; the legitimate dependency relationship and conditional setup reduce suspicion of malicious intent but do not eliminate this supply-chain risk.

Fallback setup executes downloaded installation scripts without warning about system changes or remote-code execution.

Medium
Category
Output Handling
Confidence
94% confidence
Finding

The fallback directs installation through remote shell or PowerShell execution without explicitly obtaining approval for local system changes or explaining the execution risk. Its missing-CLI condition limits exposure, but an analytics request could still lead to unreviewed code running with the invoking user's permissions; the declared tool allowlist may restrict execution but does not make these instructions safe.

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.
