Security audit

JSON修复工具免费版

Security checks for vulnerabilities and agentic risk

Overview

This JSON repair skill is not clearly malicious, but it asks for broad command execution while its instructions drift into unrelated API, network, and general automation behavior.

Review this skill before installing. It appears to be a local JSON repair helper, but its instructions are broader than necessary and could lead an agent to run shell commands, perform network troubleshooting, or treat the skill as useful for unrelated automation tasks. Use it only for explicit JSON repair on files you choose, and be aware that backup files may contain the same sensitive data as the originals.

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

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
91% confidence
Finding

The description uses broad activation language covering AI model calling, intelligent dialogue, agent orchestration, and LLM applications, far beyond JSON repair. This increases the chance the skill is selected for unrelated requests, after which its exec capability could be applied in contexts where local file repair was not intended.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
90% confidence
Finding

The capability-scope keywords are excessively broad and generic, including terms for coding assistance, deployment, and fuzzy development use cases. In an agent ecosystem, such keywords can cause accidental routing to a skill with exec permissions, making unintended command execution more likely.

Intent-Code Divergence

Medium
Category
Not specified by scanner
Confidence
95% confidence
Finding

One section claims all repairs occur locally with no external services or data exfiltration risk, while nearby sections include assumptions and troubleshooting steps for network connectivity and external API-style operation. These contradictory assurances can mislead users and agents about the trust boundary, causing sensitive data to be handled under false assumptions and normalizing unnecessary network behavior.

Description-Behavior Mismatch

Medium
Category
Not specified by scanner
Confidence
95% confidence
Finding

The skill is presented as a lightweight local JSON repair tool, but later documentation expands into API integration, external service handling, and command/network-oriented capabilities that are not justified by the stated purpose. This scope drift can cause over-broad invocation and lead an agent to perform unintended actions beyond local file repair, increasing the attack surface and enabling misuse through ambiguous task matching.

Natural-Language Policy Violations

Low
Category
Not specified by scanner
Confidence
84% confidence
Finding

The description states '支持中文交互', and the document consistently frames the skill around Chinese interaction without offering alternative language selection or opt-in. This can conflict with language or locale policy expectations when users have not chosen Chinese.

Natural-Language Policy Violations

Low
Category
Not specified by scanner
Confidence
80% confidence
Finding

The feature note says the skill covers '中文交互' as a core capability, but does not clarify that other languages are supported or that the user's preference will be respected. This creates a natural-language policy issue if the skill defaults to one language without user opt-in.

Context-Inappropriate Capability

Low
Category
Not specified by scanner
Confidence
90% confidence
Finding

Network troubleshooting guidance such as using ping and checking firewall/proxy settings is unjustified for a local JSON syntax repair skill. Even if not directly malicious, it can steer an agent into performing unrelated network diagnostics or environmental probing, which expands behavior beyond user intent and violates least privilege for this skill context.
