Bailian Web Search

Security checks for vulnerabilities and agentic risk

Overview

This skill is a straightforward Bailian web search wrapper that sends user search queries to Alibaba DashScope using the user's API key, with no hidden persistence or unrelated access observed.

Install only if you are comfortable sending your search queries to Alibaba DashScope and exposing a DashScope API key to this script's runtime environment. Avoid using sensitive secrets or private text as search queries, and consider enforcing the documented result-count maximum if cost or quota control matters.

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

Undeclared Tool Scope

Medium
Category
MCP Least Privilege
Confidence
95% confidence
Finding

The skill exposes shell execution capability through documented script invocations but does not declare any explicit tool scope or permission boundaries. This can let an agent environment grant broader-than-intended execution access, increasing the risk of command misuse, unsafe parameter handling, or unexpected shell-side effects when the skill is invoked.
