Ongage

Security checks for vulnerabilities and agentic risk

Overview

The Ongage operations have clear approval controls, but setup can execute unverified installer code and introduce broader agent changes.

Review before installing. Arrange a verified CLI installation separately and review its automatic skill synchronization before first use. Ongage data passes through OOMOL, so connect only the intended account and retain the documented approval checks for changes. The review concern is uncontrolled setup and broader dependency effects; the artifacts do not establish malicious intent.

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
  • MCP Tool PoisoningHidden Instructions, Unicode Deception, Parameter Description Injection
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
97% confidence
Finding

The supplied code executes an Oomol-hosted installer rather than performing Ongage operations. Nothing in the provided chunk establishes that this installation supports the declared Ongage functionality. The downloaded script's contents and downstream effects are not available for assessment.

Content

No source excerpt is available for this finding.

External Script Fetching

High
Category
Supply Chain
Confidence
99% confidence
Finding

The command pipes mutable network content directly into Bash without pinning a version or independently verifying integrity; the PowerShell setup uses the same execution pattern. Compromise of the distribution service could execute arbitrary code with the invoking user's permissions, potentially exposing local credentials and files, although the domain is relevant to the documented connector.

Fallback setup executes downloaded installation scripts without warning about local system changes.

Medium
Category
Output Handling
Confidence
95% confidence
Finding

A missing CLI triggers instructions to execute a remote installer without first obtaining approval for local software installation or explaining its effects. This crosses from an Ongage data task into local code execution; the conditional fallback limits exposure but does not authorize those system changes.

Content

No source excerpt is available for this finding.

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.
