camsnap

Security checks for vulnerabilities and agentic risk

Overview

This skill does what it says: it takes a webcam snapshot and saves it locally, with a normal privacy caveat for camera use.

Install only if you are comfortable with an agent being able to activate the default webcam when you ask for a snapshot. Check the saved file path after use and delete snapshots you do not want retained.

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

Missing User Warnings

Medium

Confidence: 87% confidence
Finding: The skill accesses the default webcam and writes captured images to disk without any built-in consent check, privacy notice, or confirmation mechanism in the implementation. In an agent context, that creates a real privacy risk because a misinterpreted, spoofed, or indirect instruction could trigger collection of sensitive visual data and persistence of that data on the filesystem.
