Gws Classroom

Security checks for vulnerabilities and agentic risk

Overview

The skill is a straightforward Google Classroom CLI reference that discloses read and write Classroom operations without hidden code or persistence.

Install only if you intend agents to operate Google Classroom through gws. For delete, update, invitation, roster, and registration changes, require explicit user confirmation and verify target course IDs, user IDs, and Pub/Sub topics before execution.

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: 93% confidence
Finding: The skill exposes destructive and privilege-sensitive operations such as course creation, deletion, updates, invitation management, and registration changes without any explicit warning, confirmation guidance, or safe-usage constraints. In an agent setting, this increases the chance that a user or upstream prompt could trigger irreversible or unauthorized state changes in Google Classroom through normal-looking commands.
