AgentQL

Security checks for vulnerabilities and agentic risk

Overview

The AgentQL workflow is coherent, but fallback setup executes unverified downloaded software without clear approval and can introduce broader persistent changes.

Review and approve CLI installation separately before allowing fallback setup. Understand that requests use OOMOL and that its CLI can install skills into other agent hosts. The publisher documents OO_SKILLS_SYNC_DISABLED=1 to disable startup skill synchronization in its [command reference](https://github.com/oomol-lab/oo-cli/blob/main/docs/commands.md#environment-variables). The remote installers could not be inspected, so their exact system changes remain uncertain. Preserve the skill's confirmation requirements for writes.

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
99% confidence
Finding

The supplied command installs software by executing a remotely fetched script; it does not perform any visible AgentQL operation. Nothing in the supplied content establishes this installer as a supporting dependency for AgentQL, so its purpose and external resource are inconsistent with the declaration. The downloaded script's further behavior cannot be determined from this chunk.

No source excerpt is available for this finding.

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
86% confidence
Finding

The supplied chunk performs only a CLI login, rather than implementing AgentQL operations. Authentication could be a supporting implementation detail if tied to AgentQL, but the supplied content establishes no such relationship. The authentication destination and any subsequent behavior cannot be determined from this command alone.

External Script Fetching

High
Category
Supply Chain
Confidence
98% confidence
Finding

The curl-to-bash pipeline executes the current contents of a remote installer without pinning or verifying the executable artifact. HTTPS protects transport but does not protect against a compromised distribution server or malicious installer update; this is the same underlying installation risk identified by SQP-2, not evidence that the OOMOL domain is malicious.

Fallback setup executes downloaded installation scripts without warning the user about remote code execution or system changes.

Medium
Category
Output Handling
Confidence
96% confidence
Finding

A missing dependency triggers instructions to download and immediately execute shell or PowerShell code without installation-specific approval or integrity verification. Although dependency setup is relevant to this skill, this expands a normal AgentQL request into local code execution and system changes; a compromised installer could execute arbitrary code with the invoking user's privileges.

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.
