Security audit

Contentful

Security checks for vulnerabilities and agentic risk

Overview

The skill is a coherent Contentful connector, but its first-time setup recommends unverified pipe-to-shell installers, so it should be reviewed before use.

Before installing, use a safer verified installation method for the oo CLI instead of the pipe-to-shell commands, understand that OOMOL will mediate access to your connected Contentful account, and require explicit review before any create or update action runs.

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

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.

## Available actions

- `create_entry` — Create a Contentful entry in a specific environment. [write]
- `get_current_user` — Get the authenticated Contentful user profile for the current personal access token.
- `get_entry` — Get a single Contentful entry by identifier.
- `list_content_types` — List Contentful content types available in a specific environment.
- `list_entries` — List Contentful entries with common filtering, pagination, and include options.

External Script Fetching

High
Category
Supply Chain
Confidence
98% confidence
Finding

Piping a remotely fetched script directly into bash enables arbitrary code execution if the install endpoint is compromised, intercepted, or serves unexpected content. In this skill, the danger is amplified because the instructions encourage running the command during setup, which could lead an agent or user to execute unverified code on the host.

Vague Triggers

Confidence
95% confidence
Finding

The manifest description says to use this skill for "ANY Contentful request" and "Whenever a task involves Contentful," which is an extremely broad activation condition. It does not define boundaries, exclusions, or negative examples, so ordinary mentions of Contentful could trigger the skill unnecessarily.
