Airbrake

Security checks for vulnerabilities and agentic risk

Overview

The Airbrake functions fit their stated purpose, but setup can execute unchecked downloaded software without separate approval.

Review and approve the CLI installation separately, use a verified release, and consider disabling automatic agent-skill synchronization. Connect only an appropriately limited Airbrake account and understand that OOMOL mediates access. The remote installers and hosted implementation were not verified; the supplied artifact does 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
99% confidence
Finding

The supplied code installs or runs externally supplied software rather than searching or reading Airbrake data. No connection between this installer and the declared Airbrake functionality is established. Executing a remote installation script is a materially different, undeclared capability; the script's further behavior cannot be determined from this chunk.

External Script Fetching

High
Category
Supply Chain
Confidence
99% confidence
Finding

The command pipes a mutable network response directly into Bash without pinning or independently verifying its contents; the PowerShell alternative has the same execution pattern. HTTPS protects transport but does not prevent a compromised distribution endpoint or malicious installer update from executing code with the agent's privileges and accessing locally available data.

Fallback setup instructs execution of downloaded installation scripts without warning about system changes or requesting approval.

Medium
Category
Output Handling
Confidence
97% confidence
Finding

A missing CLI triggers instructions to install software without first obtaining approval for local system changes or execution of remote code. Although this fallback is conditional, an ordinary Airbrake read request could consequently lead to arbitrary code execution with the agent process's privileges, exceeding the request's expected scope.

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.
