Caesar Cipher

Security checks for vulnerabilities and agentic risk

Overview

This is a simple Caesar cipher helper, but its referenced Python script is not included in the artifact, so users should verify the local script before relying on it.

Before installing or using this skill, confirm that the intended caesar.py implementation is present and trusted. The inspected skill text does not show hidden access or persistence, but the missing referenced script means the actual runtime behavior depends on whatever local file is executed.

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

Finding

The manifest description is written entirely in Chinese and specifies user trigger phrases in Chinese alongside one English term, without indicating that users may interact in another language. This can violate language/locale policy when a skill implicitly constrains usage to a specific language without opt-in or explicit justification.
