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

Medium

Category: Not specified by scanner
Confidence: 95% confidence
Finding: The skill is framed entirely around generating Xiaohongshu-native content and repeatedly mandates Chinese-specific title formulas, templates, hashtags, and examples. There is no indication that users may choose another language or explicitly opt into this locale-specific behavior, which is a natural-language locale policy concern under the stated rule.
Content: No source excerpt is available for this finding.
