Pywayne Cv Apriltag Detector

Security checks for vulnerabilities and agentic risk

Overview

The skill is for AprilTag detection, but it may automatically install an unpinned third-party library at runtime, so users should review it before use.

Install or run this only in a virtual environment or other contained workspace, and consider preinstalling a reviewed, pinned apriltag_detection dependency yourself. Be aware that first use may download and install third-party code through gettool with the same permissions as the running agent.

Vulnerability Patterns

Insecure DependenciesIntroduces malicious components through unsafe dependency sources
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

Missing User Warnings

Medium

Category: Not specified by scanner
Confidence: 96% confidence
Finding: The skill explicitly states that it will automatically install the apriltag_detection library via gettool if it is not already present, but it does not clearly warn users that running the skill may trigger network access, dependency downloads, and local environment modification. This is dangerous because it creates an implicit supply-chain and execution risk: users may invoke what appears to be a detection utility without realizing it can fetch and install code at runtime.
