Security audit

Wire2Air

Security checks for vulnerabilities and agentic risk

Overview

The messaging workflow has approval controls, but setup directs the agent to execute unverified online installers without a separate approval step.

Review and approve the CLI installation separately before allowing setup. Confirm whether its documented agent-skill synchronization is acceptable; the [command reference](https://github.com/oomol-lab/oo-cli/blob/main/docs/commands.md) documents a synchronization-disable setting. Connect only the intended Wire2Air account and review recipients, message content, and costs before sending. Remote installer contents and the exact installed runtime were not verified.

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
96% confidence
Finding

The supplied code executes an Oomol-hosted installer rather than interacting with Wire2Air. Dependency installation can be a supporting implementation detail, but the chunk provides no evidence that this installer is related to or required for Wire2Air functionality. The downloaded script's contents and resulting system changes cannot be determined from this chunk.

No source excerpt is available for this finding.

External Script Fetching

High
Category
Supply Chain
Confidence
98% confidence
Finding

Piping a live HTTPS response directly into bash executes mutable remote code with the invoking user's privileges, without a pinned version or independent integrity verification. Compromise of the installer distribution path could expose locally accessible files and credentials or alter the system; the related OOMOL domain and conditional setup make this plausible dependency management rather than evidence of malicious intent.

Content

The setup workflow executes downloaded installer scripts without warning about remote code execution or system changes.

Medium
Category
Output Handling
Confidence
93% confidence
Finding

The setup instructions direct an agent to execute remote shell or PowerShell installers without first explaining the local code execution and obtaining installation approval. Restricting setup to a missing CLI reduces exposure, but a request to operate Wire2Air does not necessarily authorize installing software or making other local system changes.

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.
