TextRazor

Security checks for vulnerabilities and agentic risk

Overview

The skill is mostly coherent for TextRazor use, but its fallback setup tells an agent to run remote installer scripts directly in a shell without verification.

Review the oo CLI installation path before installing. Prefer official signed packages or verified downloads where available, and require explicit approval before any setup command, login, connection change, or destructive TextRazor action is run.

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

Finding

The skill instructs users to install software via a remote script piped directly into a shell, which executes network-fetched code without verification. If the install endpoint, transport, or hosting infrastructure is compromised, this can lead to arbitrary code execution on the user's machine.

Finding

The description says to use this skill for "ANY TextRazor request" and "Whenever a task involves TextRazor, use this skill," which is extremely broad and lacks scope boundaries or negative examples. For a manifest/markdown file, this can overlap with many unrelated or indirect mentions of TextRazor and makes activation conditions unclear.
