Security audit

Dandelion API

Security checks for vulnerabilities and agentic risk

Overview

The Dandelion integration fits its purpose, but its setup can execute unchecked downloaded code and introduce broader agent-skill changes without clearly explaining them.

Review and install a verified CLI release yourself before enabling automatic setup. Check its startup skill-synchronization controls and approve broader agent-skill changes. Submit only text you intend OOMOL and Dandelion to process. The complete bundled artifact was inspected, but the external installers and exact CLI runtime effects 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 command does not search or read Dandelion data. It executes an external installer from cli.oomol.com, and the supplied content establishes no connection between that installation and the declared Dandelion functionality. The installer's contents and further effects are not visible in this chunk.

No source excerpt is available for this finding.

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
88% confidence
Finding

The supplied code performs only an authentication action, rather than the declared Dandelion search or read operations. Authentication could support API access, but this chunk provides no evidence that oo authenticates to Dandelion or implements the described functionality.

External Script Fetching

High
Category
Supply Chain
Confidence
98% confidence
Finding

The fallback installation command executes a mutable remote script directly in a shell without a pinned version or integrity verification; the PowerShell alternative has the same weakness. Although this is a legitimate CLI setup path triggered only when the tool is missing, compromise of the script distribution channel could execute attacker-controlled code with the agent process's permissions.

The workflow sends user-provided text to external services without a privacy warning.

Medium
Category
Output Handling
Confidence
90% confidence
Finding

The workflow instructs the agent to submit action payloads through OOMOL to Dandelion, including text supplied for analysis. Although the API integration is identified, there is no warning that potentially sensitive text leaves the user's environment, and line 47 treats all untagged actions as safe to run directly.

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.
