Security audit

Magyar Nyelvtan

Security checks for vulnerabilities and agentic risk

Overview

This is a small Hungarian grammar and writing-reference skill with no executable code or hidden high-impact behavior.

Before installing, understand that this skill is intended for Hungarian-language spelling, grammar, and style help. Expect possible rough edges because it references missing optional files and scripts, but there is no evidence of hidden execution, credential use, persistence, or data exfiltration.

A.I.G

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

Natural-Language Policy Violations

Finding

The manifest description and usage guidance are presented in Hungarian and the skill name itself is language-specific, but the file does not explicitly state that this skill is intentionally limited to Hungarian users or offer any user opt-in for the language constraint. Under the policy, forcing a specific language without user choice or clear justification is a natural-language policy issue.

Natural-Language Policy Violations

Finding

The title and overview frame the guidance as prescriptive Hungarian-only writing advice ("Pontos Magyar Fogalmazás", "használd az ajánlott alternatívákat") with no indication that language choice is optional. Under the policy, forcing a specific language without user opt-in is a natural-language policy violation unless the locale constraint is clearly justified.
