Security audit

Cb User Persona Builder

Security checks for vulnerabilities and agentic risk

Overview

This is a descriptive market-research persona skill with no code execution, credentials, persistence, or hidden system behavior.

This skill is safe to install from the reviewed artifacts. Treat its persona outputs as research hypotheses, avoid using them as facts about a culture or demographic, and validate any market claims with real customer evidence before making business decisions.

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

Natural-Language Policy Violations

Confidence
83% confidence
Finding

This markdown includes a full Chinese usage scenario after predominantly English examples, but it does not explain whether the skill adapts to the user's language automatically or requires explicit user choice. That can create a locale/language policy concern because the skill appears to vary output language without a documented opt-in or selection rule.

Natural-Language Policy Violations

Low
Category
Not specified by scanner
Confidence
92% confidence
Finding

The manifest explicitly sets the skill language to "en", which can indicate the skill is constrained to English. Under the policy criteria, forcing a specific language without offering user choice or documenting a justified locale constraint is a natural-language policy concern.
