Security audit

OneDesk

Security checks for vulnerabilities and agentic risk

Overview

The OneDesk functions fit their purpose, but setup runs unverified downloaded code and leaves broader changes to agent skills undisclosed.

Review the setup before installing. Use a separately verified CLI release and require approval before local installation changes. Consider whether OOMOL should mediate your OneDesk access. Upstream documents OO_SKILLS_SYNC_DISABLED=1 to prevent startup skill synchronization in its [command reference](https://github.com/oomol-lab/oo-cli/blob/main/docs/commands.md#environment-variables). The remote installer contents and exact installed release 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
98% confidence
Finding

The supplied code performs remote installer execution, not OneDesk searching or reading. Although installing a dependency can be a supporting implementation detail, nothing supplied establishes this installer's relationship to the declared OneDesk functionality. The downloaded script's contents and further effects are not shown.

External Script Fetching

High
Category
Supply Chain
Confidence
97% confidence
Finding

Piping a live HTTPS download directly into Bash executes the endpoint's current contents without release pinning, signature verification, or an opportunity to inspect the script. Compromise of the distribution endpoint could yield arbitrary code execution with the invoking user's permissions; the PowerShell example has the same weakness. The documented vendor relationship and missing-CLI trigger make this a plausible setup workflow, not evidence of malicious intent, but do not eliminate the supply-chain risk.

Content

Scanner excerpt · SKILL.md (reported line 59)May include surrounding context.

The setup workflow executes remote installation scripts without warning about local system changes or remote-code execution.

Medium
Category
Output Handling
Confidence
93% confidence
Finding

When the CLI is missing, the skill directs the agent to execute a remote installer without first explaining the local system changes or obtaining installation-specific approval. A request to read OneDesk data does not inherently authorize installing software, although the conditional setup trigger limits exposure.

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.
