Honeybadger

Security checks for vulnerabilities and agentic risk

Overview

The Honeybadger workflow requires confirmation for changes, but its setup fallback can execute an unverified remote installer without clear user approval.

Review and authorize CLI installation separately before enabling this skill. Account for its automatic skill synchronization, and confirm that OOMOL may process your Honeybadger payloads and hold the connected API key. Keep the required write confirmations. The bundled instructions were fully inspected; external installer and connector implementations remain unverified.

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
99% confidence
Finding

The supplied chunk performs remote installer execution, not Honeybadger data operations. Nothing in the provided code establishes that this installation supports the declared purpose. The downloaded script's contents are unavailable, so its further behavior cannot be determined.

Content

No source excerpt is available for this finding.

External Script Fetching

High
Category
Supply Chain
Confidence
98% confidence
Finding

The command pipes a mutable remote script directly into Bash without independently verifying its integrity or reviewing it; the PowerShell alternative has the same execution pattern. Compromise of the distribution endpoint or installer could execute arbitrary code with the agent's host privileges, exposing local data and credentials. The legitimate dependency relationship and missing-CLI condition narrow the trigger but do not remove this supply-chain risk.

Fallback setup executes remote installation scripts without warning the user about system changes.

Medium
Category
Output Handling
Confidence
92% confidence
Finding

The fallback directs the agent to install software after a missing-command error without first explaining system changes or obtaining explicit approval. Although setup is conditional, permission to perform a Honeybadger operation does not necessarily authorize installing software or executing an external installer on the host.

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.
