FullEnrich

Security checks for vulnerabilities and agentic risk

Overview

The FullEnrich lookups fit the stated purpose, but automatic setup can run unchecked downloaded code and change other agent skills without clear user approval.

Review the setup behavior before installing. Arrange a separately approved, verified CLI installation and consider disabling its automatic skill synchronization with OO_SKILLS_SYNC_DISABLED. Understand that OOMOL mediates FullEnrich requests and account access. The concern is the automatic setup and broader lasting effects; the artifacts do not establish deception or data theft. Remote installer contents could not be inspected.

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
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code
  • Excessive AgencyUnrestricted Tool Access, Autonomous Decision Making, Scope Creep
  • Output HandlingUnvalidated Output Injection, Cross-Context Output, Unbounded Output

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
99% confidence
Finding

The supplied command performs remote script execution for an Oomol CLI installer, with no visible FullEnrich interaction. This is a materially different operation from the declared data-access purpose, and the supplied code provides no evidence that the installer is a supporting dependency for FullEnrich. The remote script's contents and further effects are not available for assessment.

External Script Fetching

High
Category
Supply Chain
Confidence
98% confidence
Finding

Piping a mutable HTTPS response directly into bash executes remote code without an independently verified signature, digest, or pinned release. Compromise of the installer distribution path could therefore execute attacker-controlled code with the agent's local permissions; HTTPS and the legitimate dependency context do not eliminate this supply-chain risk.

Fallback setup executes downloaded installation scripts without a user warning.

Medium
Category
Output Handling
Confidence
95% confidence
Finding

The missing-CLI fallback directs the agent to execute a downloaded installer without first obtaining approval for local software installation or explaining its effects. Although conditional and relevant to setup, this crosses from reading service data into local code execution with the executing user's permissions.

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.
