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

Medium
Category
Not specified by scanner
Confidence
92% confidence
Finding

The file presents its core description, activation instructions, and workflow in Portuguese, which imposes a specific language on users without stating that this skill is Portuguese-only or providing a language/locale choice. This matches the language/locale policy concern for natural-language content.

Session Persistence

Medium
Category
Rogue Agent
Confidence
60% confidence
Finding

Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
92% confidence
Finding

The description is entirely in Portuguese, which implicitly constrains the skill's presentation to a specific language without indicating user choice or opt-in. Under the stated policy, fixed language selection in natural-language metadata is a violation unless the locale is explicitly justified or optional.
