Security audit

Jotform

Security checks for vulnerabilities and agentic risk

Overview

The Jotform workflow is coherent, but setup directs the agent to execute an unpinned remote installer without installation-specific approval.

Review and install a fixed CLI release yourself before use, and review or disable its automatic agent-skill synchronization. Consider whether Jotform submission data may pass through OOMOL, and retain the required confirmation before writes. Exact installer effects remain unverified; no malicious behavior was established.

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
Vulnerability Patterns

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
94% confidence
Finding

The visible code installs external tooling rather than accessing Jotform. Installation can be a supporting implementation detail, but the supplied chunk establishes no relationship between this installer and the declared Jotform functionality. The remote installer's contents are unavailable, so its further actions cannot be determined.

External Script Fetching

High
Category
Supply Chain
Confidence
98% confidence
Finding

Piping an unpinned remote script directly into bash executes whatever the endpoint serves with the invoking user's privileges, without a prior integrity check or review. A compromised distribution endpoint could therefore execute malicious code locally; the PowerShell alternative has the same underlying risk. The legitimate CLI dependency and missing-command prerequisite reduce exposure but do not eliminate this supply-chain risk.

The setup workflow executes downloaded installation scripts without warning about local code execution and system changes.

Medium
Category
Output Handling
Confidence
94% confidence
Finding

The fallback instructs the agent to install software by executing remote scripts without explaining local execution privileges or obtaining installation-specific approval. Conditioning this on a missing CLI limits exposure, but a Jotform data request does not inherently authorize arbitrary local software installation; actual execution also depends on the host's tool permissions.

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.

External Transmission

Medium
Category
Data Exfiltration
Confidence
50% confidence
Finding

Data is being sent to an external URL. This could be legitimate telemetry or data exfiltration. Manual review is recommended.
