Security audit

UAPI 每日新闻图 接口

Security checks for vulnerabilities and agentic risk

Overview

This skill is a narrow, disclosed wrapper for fetching a public daily news image from UAPI, with no local code execution, persistence, or hidden data access.

Before installing, be aware that broad phrases like daily digest may activate this skill and make a request to UAPI for a news image. It appears safe for its stated purpose, but users who want strict control over external calls may prefer explicit invocation or narrower triggers.

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
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Trigger AbuseOverly Broad Trigger, Shadow Command Trigger, Keyword Baiting Trigger
  • 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
91% confidence
Finding

The trigger list includes broad, everyday phrases such as "daily digest" and "news poster," which can match requests that are not specifically about this UAPI endpoint. This increases the chance of unintended skill invocation, causing the agent to select a narrower external API action than the user intended and potentially route data or workflow decisions incorrectly.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
93% confidence
Finding

The manifest sets allow_implicit_invocation: true, which permits the skill to be triggered without tightly constrained user intent or explicit invocation boundaries. Even though this skill only targets a read-style GET endpoint for a daily news image, broad implicit activation increases the chance of unintended tool use, parameter misuse, or prompt-driven invocation when the user did not clearly request this external action.

Natural-Language Policy Violations

Confidence
80% confidence
Finding

The natural-language description is presented in both Chinese and English, but the document does not state how the assistant should choose the response language or defer to user preference. This can conflict with language/locale policy expectations when a skill effectively imposes a language choice without explicit opt-in.

Confidence
87% confidence
Finding

This markdown file contains only Chinese-language user-facing instructions and descriptions, with no indication that users may choose another language or that the locale restriction is intentional. Under the policy rule, forcing a specific language without opt-in is a natural-language policy concern.

Natural-Language Policy Violations

Category

Confidence
77% confidence
Finding

The file is primarily written in Chinese, but the keyword index also prescribes English trigger phrases. This creates an implicit language behavior without clarifying whether the skill should match one language, both, or based on user preference, which can conflict with language/locale policy expectations.
