Rootly

Security checks for vulnerabilities and agentic risk

Overview

The Rootly workflow is appropriate, but its setup can execute unverified remote installers without a clear user approval step.

Review the setup before enabling this skill. Install a reviewed, version-pinned CLI yourself and require approval for software installation or changes to other agent skills. Use read-only Rootly access where available and understand that OOMOL mediates account access. The remote installer could not be retrieved for inspection.

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
Vulnerability Patterns

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
99% confidence
Finding

The supplied command does not search or read Rootly data. It fetches and executes an Oomol installation script, with no demonstrated connection to Rootly functionality. This is a materially different operation involving an inconsistent resource, rather than an established supporting implementation detail. The downloaded script's further behavior cannot be determined from this chunk.

External Script Fetching

High
Category
Supply Chain
Confidence
98% confidence
Finding

The command executes a mutable remote script immediately without signature verification, a pinned digest, or review; the PowerShell alternative has the same issue. Compromise of the distribution endpoint or installer could execute arbitrary code with the agent's local permissions, exposing files and credentials even though Rootly credentials are injected server-side. The legitimate dependency and conditional setup reduce suspicion of malicious intent but do not remove the supply-chain risk.

The setup fallback instructs the agent to execute downloaded installation scripts without warning the user about local system changes.

Medium
Category
Output Handling
Confidence
94% confidence
Finding

The fallback directs the agent to install software on the local system without first explaining the changes or obtaining explicit approval. A request to read Rootly data does not necessarily authorize local software installation, although the missing-command condition limits when this risk arises.

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.
