Security audit

Typebot

Security checks for vulnerabilities and agentic risk

Overview

The Typebot reading functions fit the stated purpose, but setup can execute unverified installers and introduce broader agent changes without clear user control.

Review and install a specific CLI release yourself before enabling this skill, and decide whether OOMOL should handle your Typebot credentials and results. Require approval for dependency installation. To prevent the documented startup skill synchronization, set OO_SKILLS_SYNC_DISABLED=1 before CLI use; see [publisher controls](https://github.com/oomol-lab/oo-cli/blob/main/docs/commands.md#environment-variables). The bundled skill was fully inspected, but the remote installers and deployed connector implementation remain unverified.

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

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
99% confidence
Finding

The supplied chunk performs remote script execution rather than searching or reading Typebot data. It accesses an Oomol installation endpoint, and nothing in the supplied code establishes that this installation is a supporting implementation detail required for the declared Typebot functionality. The downloaded script's contents and any further effects are not available for assessment.

Content

No source excerpt is available for this finding.

External Script Fetching

High
Category
Supply Chain
Confidence
98% confidence
Finding

The command executes a remotely supplied script immediately, without version pinning, signature verification, or an opportunity to inspect it; the PowerShell alternative has the same issue. Compromise of the distribution endpoint or release pipeline could execute attacker-controlled code with the agent's local permissions, exposing files and credentials even though this is a legitimate dependency-installation context.

Content

Scanner excerpt · SKILL.md (reported line 60)May include surrounding context.

The setup workflow instructs the agent to execute remote installation scripts without warning the user about local system changes.

Medium
Category
Output Handling
Confidence
92% confidence
Finding

On a missing-command error, the skill directs the agent to install software without first disclosing local changes or obtaining installation approval. A request to read Typebot data does not necessarily authorize modifying the local environment, although the missing-dependency condition limits when this behavior occurs.

Autonomous Decision Making

Medium
Category
Excessive Agency
Confidence
80% confidence
Finding

Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.
