SQLite Query and Export Desk

Security checks for vulnerabilities and agentic risk

Overview

The skill’s database operations match its description, and its bundled network helper is unused by the supported actions.

Use a separate workspace containing the files you intend to process. Exported reports can contain sensitive database records and remain on disk; remove them when no longer needed.

A.I.G

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

Findings (5)

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
88% confidence
Finding

The reported implementation exposes outbound HTTP operations, including state-changing methods and opt-in private-network access, beyond the advertised local SQLite workflow. If reachable through skill inputs, these capabilities could transmit sensitive database contents or interact with internal services; explicit host opt-in and approval instructions reduce exposure but do not resolve the undisclosed capability mismatch. This assessment relies on the static finding because the implementation and its enforcement controls were not supplied.

Content

No source excerpt is available for this finding.

Credential Access

High
Category
Privilege Escalation
Confidence
60% confidence
Finding

Code accesses credential files (SSH keys, AWS credentials, etc.). This could indicate credential theft attempts.

Skill declares no tool scope ('permissions' or 'allowed-tools') but code capabilities were detected: file_read, file_write, network, shell.

Medium
Category
MCP Least Privilege
Confidence
70% confidence
Finding

Without declared permissions the skill's intent is opaque and cannot be validated.

Content

No source excerpt is available for this finding.

The SQLite-only skill includes a general-purpose HTTP client capable of remote mutations.

Medium
Category
Excessive Agency
Confidence
98% confidence
Finding

The manifest describes local SQLite inspection, bounded read-only queries, and CSV/JSON import/export, none of which requires network access. The safe_request helper implements outbound HTTP requests with caller-supplied headers and bodies, including POST, PUT, PATCH, and DELETE, providing an unrelated remote-resource modification capability. This file defines the capability but does not show it being invoked.

Content

Scope Creep

Low
Category
Excessive Agency
Confidence
70% confidence
Finding

Skill's behavior or capabilities extend beyond its stated purpose. Scope creep allows an agent to perform actions unrelated to its documented functionality, increasing the attack surface.
