Oschina

Security checks for vulnerabilities and agentic risk

Overview

This skill is a lightweight OSChina public-content helper with no executable code, persistence, credential use, or hidden high-impact behavior.

Install only if you want the agent to help browse and summarize public OSChina content. Keep requests specific, and avoid asking it to bypass OSChina access controls, solve human checks automatically, or collect content in bulk.

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

Vague Triggers

Medium

Category: Not specified by scanner
Confidence: 93% confidence
Finding: The skill description is broad enough that it could be invoked for generic requests related to OSChina content, rather than only narrowly scoped, user-intended automation. Overbroad trigger text can cause inappropriate tool selection, increasing the chance of unneeded browsing, data collection, or action on external sites without sufficiently specific user consent.
Content: No source excerpt is available for this finding.
