Security checks for vulnerabilities and agentic risk

Overview

This skill is a disclosed local wiki-index workflow with minor data-safety and language-usability caveats, not evidence of malicious behavior.

Install only if you want a Chinese-language local wiki index. Keep control of wiki/wiki.json, validate JSON before restoring from wiki.json.bak, and review referenced memory/source paths before loading private details.

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
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • 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
Findings (3)

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
93% confidence
Finding

The entire skill design document is written exclusively in Chinese and does not indicate that language choice is optional or limited to a justified region-specific context. Under the policy rule, forcing a specific language without user opt-in is a natural-language policy concern.

No source excerpt is available for this finding.

Missing User Warnings

Medium
Category
Not specified by scanner
Confidence
90% confidence
Finding

The skill instructs direct backup overwrite and restore operations using cp without any integrity validation, versioning, or warning about clobbering newer data. In this context, a malformed, stale, or attacker-tampered backup could silently replace the live index, causing data loss or persistence of poisoned entries that shape later retrieval behavior.

Natural-Language Policy Violations

Low
Category
Not specified by scanner
Confidence
76% confidence
Finding

The document presents all instructions, labels, and examples in Chinese and does not indicate that users may choose another language or locale. Under the policy, forcing a specific language without user opt-in is a natural-language policy concern unless the locale restriction is explicitly documented and justified.
