GitLab

Security checks for vulnerabilities and agentic risk

Overview

This GitLab skill is coherent and disclosed, but it combines broad GitLab mutation authority with a risky remote shell installer that users should review before installing.

Install only if you are comfortable routing GitLab operations through OOMOL and giving the connected account the listed GitLab powers. Avoid running the remote installer blindly; prefer a verified package, checksum/signature validation, or inspecting the installer first. Confirm all write, merge, update, and delete payloads carefully before execution.

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

Credential Access

High
Category
Privilege Escalation
Confidence
70% confidence
Finding

Code accesses credential files (SSH keys, AWS credentials, etc.). This could indicate credential theft attempts.

External Script Fetching

High
Category
Supply Chain
Confidence
98% confidence
Finding

The skill recommends installing software via a remote script piped directly into a shell, which is a classic supply-chain and remote code execution risk. If the install endpoint, transport, or upstream distribution is compromised, the user may execute attacker-controlled code immediately on their machine.

Finding

The description says to use this skill for "ANY GitLab request" and "Whenever a task involves GitLab," which is an extremely broad activation condition. It does not define boundaries, exclusions, or negative examples, so the skill could be invoked for a wide range of ordinary GitLab-related mentions beyond the intended scope.
