Security audit

New Relic

Security checks for vulnerabilities and agentic risk

Overview

Review before installing: setup executes unverified downloaded code, and the required CLI can silently install additional persistent agent skills.

Review and verify the CLI installation before allowing setup. Decide whether additional agent skills should be installed; the CLI documents OO_SKILLS_SYNC_DISABLED=1 to suppress startup synchronization in its [command reference](https://github.com/oomol-lab/oo-cli/blob/main/docs/commands.md#environment-variables). Use narrowly scoped New Relic credentials and retain the required approvals for changes and deletions. The remote installer and hosted connector implementation 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
98% confidence
Finding

The supplied command installs software from Oomol rather than performing any visible New Relic operation. Although installation can be a supporting implementation detail, the supplied chunk provides no evidence that this installer supports the declared New Relic functionality. The downloaded script's contents and further effects are not available for assessment.

External Script Fetching

High
Category
Supply Chain
Confidence
98% confidence
Finding

The setup command pipes a remotely fetched, unpinned script directly into Bash without integrity verification or review; the PowerShell example uses the equivalent fetch-and-execute pattern. Compromise of the installer distribution could execute attacker-controlled code with the agent process's permissions, exposing local files and credentials. The legitimate dependency relationship and missing-CLI precondition reduce exposure but do not establish the downloaded code's integrity.

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.
