Clari Copilot

Security checks for vulnerabilities and agentic risk

Overview

The Clari Copilot features fit the stated purpose, but setup directs execution of unverified installation code without a clear approval step.

Review and approve CLI installation separately, preferably using a pinned, verified release. Check its automatic skill synchronization before running it in an existing agent environment. Be comfortable with OOMOL mediating access to private Clari call data and connection credentials. The bundled instructions were fully inspected, but the external installers, CLI binary, and live service behavior were not verified.

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 declared purpose concerns accessing Clari Copilot data, but the supplied code executes an installer hosted on an unrelated domain. Nothing in the chunk establishes that this installation supports Clari Copilot functionality. The downloaded script is not supplied, so its specific effects cannot be determined.

External Script Fetching

High
Category
Supply Chain
Confidence
98% confidence
Finding

Piping an unpinned remote script directly into Bash executes whatever the endpoint serves with the invoking user's privileges, without prior integrity verification or review. A compromised distribution endpoint could therefore execute arbitrary code or access local secrets; HTTPS and the legitimate dependency context do not eliminate that supply-chain risk. The PowerShell installation example has the same weakness.

The setup workflow instructs the agent to execute a downloaded installer without warning the user about the system changes or remote-code execution.

Medium
Category
Output Handling
Confidence
95% confidence
Finding

On a missing-command error, the setup instructions direct installation without first explaining the execution of remote code or obtaining approval for local system changes. This crosses beyond the expected read-only data workflow; the conditional trigger and declared Bash(oo *) restriction reduce exposure, but do not make the installation 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.
