Security audit

Dangdang

Security checks for vulnerabilities and agentic risk

Overview

This is a straightforward Dangdang book-shopping and reading-advice skill with no code, persistence, credential access, or hidden high-impact behavior.

Safe to install for book recommendations and Dangdang shopping strategy. Treat promotion and price advice as general guidance because real prices and coupons change at checkout, and choose legitimate sources since the skill explicitly avoids piracy resources.

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

Low

Category: Not specified by scanner
Confidence: 82% confidence
Finding: The manifest description at L004 is bilingual, while the main skill instructions from L010-L012 are written as if the assistant should operate in Chinese by default. Because the file does not explicitly offer the user a language preference or opt-in, this can be read as forcing a specific language behavior.
Content: No source excerpt is available for this finding.
