Security audit

Rss Aggregator

Security checks for vulnerabilities and agentic risk

Overview

This skill is a simple RSS briefing workflow with disclosed, purpose-aligned web fetching and low-impact local history logging for deduplication.

Before installing, be aware that the skill will fetch RSS/article content from the configured sources and maintain a local pushed_history.log of pushed titles and links. Review or change the RSS list, and consider adding an explicit storage path and retention limit if you run it frequently.

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
  • 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
  • Excessive AgencyUnrestricted Tool Access, Autonomous Decision Making, Scope Creep

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
93% confidence
Finding

The README description is written entirely in Chinese and does not indicate that users may choose another language or locale. Under the policy rule, forcing a specific language without user opt-in is a natural-language policy violation.

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
93% confidence
Finding

The file mandates Chinese headings and output template text such as 今日AI资讯, 标题:, 摘要:, and 链接: across the entire skill, but does not state that this is optional or region-specific. This creates a language-policy issue because the skill imposes a specific language/locale without user opt-in.

Missing User Warnings

Medium
Category
Not specified by scanner
Confidence
96% confidence
Finding

The skill explicitly instructs the agent to read and then append to a local pushed_history.log file, creating persistent side effects on the host without any user notice, confirmation, or scope limitation. This is dangerous because a skill can silently modify local state, affect future runs, and potentially overwrite or grow files in ways the user did not authorize, even if the stated purpose is benign deduplication.
