Security checks for vulnerabilities and agentic risk

Overview

This skill is a Spanish sales-webinar builder that creates local slide and script files, with no evidence of hidden exfiltration, persistence, credential access, or destructive behavior.

Install this if you want a Spanish-language sales webinar workflow. Review any business briefs, client cases, screenshots, or context files before use, because the skill may incorporate local business context into generated slides and scripts. The HTML template loads Google Fonts and includes local copy/download controls, but no evidence of data exfiltration was found.

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
87% confidence
Finding

The trigger description is quite broad and includes common webinar-related phrases, which can cause the skill to activate for general educational or presentation-help requests that do not actually fit this sales-webinar workflow. That over-broad routing can lead to irrelevant prompting, unnecessary collection of business-sensitive context, and the model steering users into a sales framework they did not ask for.

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
96% confidence
Finding

The rule mandating a specific language variant ('Tutea' and 'Nada de voseo') overrides user preference and can produce outputs mismatched to the user's locale or audience. While not a classic security bug, it is a genuine safety/quality issue because it can degrade trust, create social-engineering friction, and cause the agent to ignore explicit user communication norms.

Finding

The root HTML tag sets lang="es", and the visible UI text throughout the file is exclusively Spanish. Under the policy rule, forcing a specific language without opt-in can be a natural-language locale violation when no user choice or justification is provided.
