Security audit

UAPI 程序员历史上的今天 接口

Security checks for vulnerabilities and agentic risk

Overview

This skill is a small, disclosed wrapper for a public UAPI “programmer history today” endpoint, with only minor routing and language-scope caveats.

Installing this skill is reasonable if you want an agent to use UAPI for programmer-history-on-this-day queries. Be aware that the broad 'today' trigger could activate it for unrelated date requests, and API use may contact uapis.cn or require a UAPI key if anonymous quota is exhausted.

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
95% confidence
Finding

The trigger list includes the standalone English keyword "today," which is extremely broad and likely to match many unrelated user requests. This can cause unintended invocation of this skill, leading the agent to choose an irrelevant external API path and potentially disclose user context to a third-party service when the user did not intend that action.

Vague Triggers

Category

Confidence
97% confidence
Finding

Listing "today" as a common keyword without any scope restriction makes the skill eligible for broad accidental matches during intent selection. In a tool-using agent, that increases the chance of misrouting benign requests into an external API workflow, which may create privacy, reliability, and least-privilege issues.

Natural-Language Policy Violations

Low
Category
Not specified by scanner
Confidence
77% confidence
Finding

The display name, short description, and default prompt are all written only in Chinese, which can impose a language preference without any indication that the user may choose another language. The policy requires flagging language or locale constraints when they are forced without user opt-in or documented justification.

Natural-Language Policy Violations

Confidence
89% confidence
Finding

This markdown file presents the skill description, usage guidance, and response information entirely in Chinese. Per the policy, forcing a specific language without user opt-in can be a natural-language policy violation when no alternative language or locale choice is offered.
