Security audit

QuintaDB

Security checks for vulnerabilities and agentic risk

Overview

Review is needed because a missing prerequisite can trigger downloaded installer code without a clear user approval step.

Review and approve CLI installation separately, verify the release, and check its automatic skill synchronization before allowing setup. Connect only the intended QuintaDB account and confirm every write or deletion. OOMOL mediates database access; installer contents 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
97% confidence
Finding

The supplied code executes an Oomol CLI installer rather than performing QuintaDB operations. No connection between this installation and the declared QuintaDB functionality is established. The downloaded script is not supplied, so its additional behavior cannot be assessed.

Content

No source excerpt is available for this finding.

External Script Fetching

High
Category
Supply Chain
Confidence
98% confidence
Finding

The command pipes an unpinned HTTPS response directly into bash, allowing the installation endpoint to supply code that executes with the invoking process's privileges. Compromise of the endpoint or its delivery infrastructure could expose local files and credentials or enable persistent changes; HTTPS alone does not establish the integrity of the script. This is a legitimate prerequisite-installation context, not evidence of malicious intent, and it overlaps with SQP-2.

Content

First-time setup executes downloaded installer scripts without warning about local system changes or remote-code execution.

Medium
Category
Output Handling
Confidence
95% confidence
Finding

The setup instructions direct installation through remotely downloaded shell or PowerShell scripts without requiring user approval or explaining that arbitrary code will run locally. A request to operate QuintaDB could therefore trigger local software installation with the agent's privileges; the missing-CLI condition limits exposure but does not establish consent for those changes.

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.
