Security checks for vulnerabilities and agentic risk

Overview

This skill coherently creates temporary RooQuiz preview links, with the main caution that quiz content is sent to an external preview service.

Install only if you are comfortable sending the quiz's questions, answers, labels, and report text to RooQuiz's hosted preview service. Avoid using confidential or regulated material in hosted previews, and use the documented self-hosted endpoint overrides for private deployments.

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
Vulnerability Patterns
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code
  • Excessive AgencyUnrestricted Tool Access, Autonomous Decision Making, Scope Creep

External Transmission

Medium
Category
Data Exfiltration
Confidence
92% confidence
Finding

The skill instructs the agent to send arbitrary quiz JSON to a third-party public endpoint and return a browser-openable link. If the quiz content includes sensitive, proprietary, regulated, or user-provided personal data, the skill causes external data transmission to an unauthenticated external service without any built-in consent gate, redaction step, or data-classification check.

Content

Scanner excerpt · SKILL.md (reported line 45)May include surrounding context.

For example, with curl (write the JSON to a file first, or inline it with --data):

bash
curl -sS -X POST https://preview.rooquiz.com/api/preview-forms \
  -H 'Content-Type: application/json' \
  --data-binary @/tmp/preview-form.json

Natural-Language Policy Violations

Low
Category
Not specified by scanner
Confidence
95% confidence
Finding

The file states that the form language defaults to zh_CN, which imposes a specific locale if the user does not actively choose another value. Under the policy, forcing a language or locale without opt-in is a natural-language policy concern unless the constraint is clearly justified or choice is explicitly offered up front.
