Security audit

Ahrefs

Security checks for vulnerabilities and agentic risk

Overview

The skill is mostly coherent for Ahrefs access, but its setup instructions tell users to execute an unverified remote installer directly in a shell.

Install only if you trust OOMOL and are comfortable with the oo CLI handling Ahrefs access. Avoid running the pipe-to-shell installer as written; prefer official installation documentation, pinned releases, and checksum or signature verification before executing any installer.

Vulnerability Patterns
  • Remote Payload Retrieval and ExecutionFetches external code whose behavior can change after review
  • 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
  • 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 the shell (curl ... | bash), which executes unverified code from the network with no integrity check or review step. If the install endpoint, transport, DNS, or hosting is compromised, this can lead to arbitrary code execution on the user's machine.

Finding

The description says to use this skill for "ANY Ahrefs request" and "Whenever a task involves Ahrefs," which is extremely broad and overlaps with many ordinary tasks that merely mention Ahrefs. The file does not provide narrowing conditions, explicit trigger phrases, or negative examples to distinguish when this skill should or should not activate.
