Security audit

Tender Writer

Security checks for vulnerabilities and agentic risk

Overview

This skill is a disclosed Chinese tender-proposal writing helper with no executable code, persistence, hidden privilege use, or deceptive behavior found.

Before installing, be aware that this skill is intended for Chinese tender/proposal workflows and may handle sensitive procurement files. Review generated bid content for accuracy and compliance, and only allow Feishu delivery when you intend to share the resulting document that way.

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
Vulnerability Patterns
  • Trigger AbuseOverly Broad Trigger, Shadow Command Trigger, Keyword Baiting Trigger
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
97% confidence
Finding

The skill description includes broad trigger phrases such as '投标', '标书', '技术方案', and '招标文件', which are common business terms and can easily appear in ordinary user conversations. This can cause unintended activation of the skill, leading it to process sensitive procurement documents or generate authoritative-seeming bidding content when the user did not explicitly intend to invoke it.

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
95% confidence
Finding

The description is written as a Chinese-language tender proposal generator and specifies generating a Word-format bid technical proposal, but it does not indicate that users can choose another language or that the Chinese locale is a justified constraint. This can violate language/locale policy because it appears to enforce a specific language without opt-in.
