Security audit

Xata

Security checks for vulnerabilities and agentic risk

Overview

The Xata read workflow is coherent, but setup runs unverified remote code and leaves broader agent changes undisclosed.

Review setup before installing. Prefer a verified CLI version installed under your control, and use a Xata key limited to needed reads. Confirm you accept OOMOL brokering the connection. The current [CLI reference](https://github.com/oomol-lab/oo-cli/blob/main/docs/commands.md) documents OO_SKILLS_SYNC_DISABLED=1 to prevent automatic skill synchronization. The remote installer and hosted connector implementation 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
99% confidence
Finding

The supplied command performs remote installer execution, with no visible Xata interaction. Installing software from Oomol is materially different from the declared Xata data-access purpose, and the chunk provides no evidence that this is a supporting dependency for that purpose. The downloaded script's further behavior cannot be determined from the supplied code.

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
92% confidence
Finding

The supplied chunk only invokes a login command; it contains no Xata search or read operation. Authentication could be a supporting implementation detail, but nothing in this chunk establishes that oo auth login authenticates to Xata or supports the declared functionality.

External Script Fetching

High
Category
Supply Chain
Confidence
99% confidence
Finding

Piping an HTTPS download directly into bash executes mutable remote content without a verification or review step. Compromise of the installer distribution infrastructure could result in arbitrary code execution with the agent process's permissions; the legitimate dependency and conditional setup reduce exposure but do not remove this supply-chain risk.

First-time setup executes remote installation scripts without warning about the system-integrity implications.

Category
Output Handling
Confidence
96% confidence
Finding

The setup instructions direct the agent to execute downloaded shell or PowerShell code without explaining that this grants the installer the current user's execution privileges or requiring explicit installation approval. The missing-CLI condition limits exposure, but requesting Xata reads does not necessarily authorize system changes or execution of mutable third-party code.

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.
