Volcengine Network Dns

Security checks for vulnerabilities and agentic risk

Overview

This skill is a DNS management helper, but its broad activation wording and under-scoped DNS mutation guidance mean users should review it before installation.

Install only if you intend to let an agent help with Volcengine DNS administration. Before using it, restrict it to DNS-specific requests, require explicit confirmation for create/update/delete operations, verify the target domain and record ID, and use a least-privilege Volcengine API key rather than a broad account key.

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

  • Trigger AbuseOverly Broad Trigger, Shadow Command Trigger, Keyword Baiting Trigger

Vague Triggers

High
Category
Not specified by scanner
Confidence
97% confidence
Finding

The description says the skill should be used when users need project management, task planning, progress tracking, or team collaboration, which are broad everyday scenarios and do not match the DNS-specific purpose. This makes the activation scope ambiguous and could cause unintended invocation outside the intended networking/DNS domain.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
93% confidence
Finding

The summary fields end with fragments like 'Use when users' without any concrete trigger phrases or scope constraints. Because the activation condition is unfinished and unspecified, users and orchestrators cannot reliably distinguish when this skill should or should not activate.

Intent-Code Divergence

Medium
Category
Not specified by scanner
Confidence
95% confidence
Finding

The description says the skill is for Volcengine DNS record management, query, and update, but it also states it should be used for project management, task planning, progress tracking, and team collaboration. Those statements describe a different kind of skill and actively conflict with the DNS-focused functionality documented throughout the rest of the file.

Missing User Warnings

Medium
Category
Not specified by scanner
Confidence
89% confidence
Finding

The skill describes deletion of DNS records and notes irreversibility, but it does not present a prominent upfront safeguard, confirmation requirement, or restricted workflow in the overview/usage path. In an agent context, ambiguous destructive capability can lead to accidental service disruption, domain outage, or loss of critical routing records if the agent performs deletions without strong user confirmation.
