Security audit

Mediawiki Wikitext

Security checks for vulnerabilities and agentic risk

Overview

This skill is a static MediaWiki wikitext reference with no executable code, persistence, credential access, or hidden behavior.

This appears safe to install for help writing MediaWiki or Wikipedia wikitext. Be aware it may be invoked for broad Wikipedia-related requests, so users may need to clarify when they want factual research rather than markup formatting help.

A.I.G

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

94% confidence
Finding
The manifest says the skill should be used when creating or editing wiki articles, generating wikitext content, or converting content to wikitext, then adds that it triggers on requests mentioning 'Wikipedia, MediaWiki, wikitext, wiki markup, or wiki article creation.' This mixes clear domain terms with a broad activation description and provides no exclusion conditions or negative examples, increasing the chance of unintended invocation on general Wikipedia-related requests.
