Security audit

UniOne

Security checks for vulnerabilities and agentic risk

Overview

The UniOne workflow includes safeguards, but its automatic setup executes remote code without separate approval or clear limits on local changes.

Review setup before enabling this skill. Install a verified, fixed CLI version under your control and assess its automatic skill synchronization before first use. OOMOL processes the requested UniOne operations, so review the connected account's permissions and confirm email recipients and content. The installer payload and hosted connector implementation were not verified; the available evidence does not establish malicious behavior.

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

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
97% confidence
Finding

The supplied code performs remote script execution rather than any visible UniOne data operation. Installation can be a supporting implementation detail, but nothing supplied establishes that this Oomol installer supports the declared UniOne functionality. The downloaded script's specific actions cannot be determined from this command alone.

Content

No source excerpt is available for this finding.

External Script Fetching

High
Category
Supply Chain
Confidence
97% confidence
Finding

The command pipes a mutable remote script directly into bash without checking a pinned version, signature, or independently trusted checksum. HTTPS protects transport but does not prevent a compromised distribution endpoint from serving malicious code, which would execute with the agent's local privileges; the PowerShell alternative has the same underlying risk.

Fallback setup executes remote installer scripts without warning about their system-level effects.

Medium
Category
Output Handling
Confidence
92% confidence
Finding

The missing-CLI fallback directs the agent to execute remote installation scripts without first explaining local system changes or obtaining installation-specific approval. Although this is a legitimate setup dependency rather than an unrelated action, installer code can modify files and access resources available to the executing account; the listed tool restriction may constrain execution but is not a substitute for safe setup instructions.

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.
