Security audit

JidoSeal OKF check

Security checks for vulnerabilities and agentic risk

Overview

This skill is a disclosed local Markdown-frontmatter checker and fixer, with a supply-chain caution because its external MCP dependency is not version-pinned.

Before installing, be aware that this skill uses an external local MCP package and can edit Markdown frontmatter in the folder you choose. Review the proposed file changes before approving them, consider using version control or a backup, and only start checkout if you intentionally want the optional paid certificate.

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
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
  • Excessive AgencyUnrestricted Tool Access, Autonomous Decision Making, Scope Creep

Finding

The skill instructs users to install and execute an MCP server package without pinning a specific version, which means future installs may silently pull a different release than the author reviewed. Because this package is then used as a local tool with file-system access over user-selected folders, a compromised or malicious upstream release could execute unintended code or alter results.

Confidence

Finding

The documentation tells users to run pip install jidoseal-mcp without a version constraint, so installations are not reproducible and may fetch an unexpected newer package. In this skill's context, that package becomes part of the toolchain the agent relies on, so an upstream supply-chain compromise could affect local scanning behavior or execute arbitrary code during installation or use.
