Security audit

Birdnet

Security checks for vulnerabilities and agentic risk

Overview

This skill is a straightforward read-only wrapper for a user’s BirdNET-Go server, with minor configuration hygiene considerations.

Install only if you intend to let the skill query your BirdNET-Go instance. Keep the config URL pointed at a trusted local server, and avoid placing API keys or unrelated secrets in the birdnet config file.

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

Undeclared Tool Scope

Medium

Category: MCP Least Privilege
Confidence: 86% confidence
Finding: The skill invokes shell commands (bash scripts/birdnet.sh ...) but does not declare any explicit tool scope such as permissions or allowed-tools. That weakens execution boundaries and can allow broader-than-intended command execution in agents that rely on manifest-declared scopes for enforcement or user review.
