Security checks for vulnerabilities and agentic risk

Overview

This skill is a disclosed opcmenu integration that handles account actions only with user authorization and clear boundaries.

Install only if you intend to use opcmenu. Account actions can send messages, submit or change signups, modify profile data, export attendee information, disclose contact details, or spend credits, so review prompts carefully and authorize only the specific action you want.

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

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
81% confidence
Finding

The manifest description is written entirely in Chinese and presents the skill behavior in that language, which can be interpreted as a language constraint. The file does not explicitly offer a language or locale choice in the manifest section, so this may violate the policy against forcing a specific language without user opt-in.

Data Exfiltration

Finding

Data is being sent to an external URL. This could be legitimate telemetry or data exfiltration. Manual review is recommended.

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
95% confidence
Finding

The entire workflow documentation is written only in Chinese and does not indicate any user language choice, fallback, or opt-in for locale. Under the policy rule, forcing a specific language without explicit user choice is a natural-language policy violation unless clearly justified as region-specific.
