WikiLocal Personal Knowledge Wiki

Security checks for vulnerabilities and agentic risk

Overview

This is a local personal-wiki skill that writes and searches markdown files on the user's machine, with no evidence of hidden network access, credential use, privilege escalation, or destructive behavior.

Install only if you want an agent to maintain a local markdown wiki. Keep backups of important notes, and ask the agent to confirm before adding or replacing articles if accidental local edits would matter to you.

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

Medium
Category
Not specified by scanner
Confidence
86% confidence
Finding

The usage examples imply that natural-language phrases like 'Add to wiki' and 'wiki search' can trigger state-changing actions, but they do not define strict trigger boundaries, confirmation requirements, or authorization constraints. In an agent setting, broad conversational triggers can cause unintended edits from ambiguous user input, quoted text, or prompt-injected content, making unauthorized or accidental modification of the local knowledge base more likely.

Missing User Warnings

Medium
Category
Not specified by scanner
Confidence
90% confidence
Finding

The add() method writes article content to a markdown file and updates a persistent JSON index, which affects user data on disk. The code contains no confirmation prompt, logging, or explanatory comment/docstring disclosing that invoking this method will persist and modify local files.

Missing User Warnings

Medium
Category
Not specified by scanner
Confidence
93% confidence
Finding

When relatedTo entries are provided, the method silently creates new stub markdown files for missing related articles and updates the index. This is a non-obvious side effect beyond saving the requested article, and there is no user-facing disclosure or warning in the code.

Scope Creep

Low
Category
Excessive Agency
Confidence
70% confidence
Finding

Skill's behavior or capabilities extend beyond its stated purpose. Scope creep allows an agent to perform actions unrelated to its documented functionality, increasing the attack surface.
