Security audit

Emmestudio Brand

Security checks for vulnerabilities and agentic risk

Overview

This skill is a coherent EmmeStudio brand-guidance package with no executable code, persistence, or hidden data handling.

Install this if you want Codex to apply EmmeStudio's Italian brand system to documents and presentations. Be aware that its trigger language is broad, so users should explicitly mention when EmmeStudio branding is or is not desired, and only access the referenced Google Drive resources through authorized accounts.

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

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
94% confidence
Finding

The activation description is very broad and overlaps with common user requests such as creating documents, presentations, letters, or any formatted output. This can cause the skill to trigger in situations beyond true EmmeStudio-branded content, leading to unintended instruction injection into unrelated tasks and increasing the chance of unauthorized branding, data mixing, or workflow interference.

Vague Triggers

Medium
Category

Confidence
90% confidence
Finding

The scope definition for when the skill activates is ambiguous because terms like 'represents EmmeStudio toward the outside' and 'formal internal documents' are subjective and open to broad interpretation. In an agentic system, this ambiguity can make the skill activate on many ordinary tasks, causing overreach into unrelated outputs and making downstream behavior less predictable and easier to abuse.

Natural-Language Policy Violations

Finding

This markdown file contains natural-language instructions exclusively in Italian, but it does not state that the skill is intended only for Italian-speaking users or offer any language/locale choice. Under the policy, forcing a specific language without user opt-in can be a natural-language policy violation.

Natural-Language Policy Violations

Confidence
91% confidence
Finding

The template rules require fixed Italian expressions such as "Offerta per...", "Spett.le", "Gentile", and "Bergamo, lì ...". This is a natural-language locale constraint, and the file does not indicate that users may choose another language or that the restriction is required for a region-specific compliance purpose.
