Formsite

Security checks for vulnerabilities and agentic risk

Overview

The skill is mostly a coherent Formsite connector, but its setup instructions include unverified remote install commands that can execute changing code on a user's machine.

Review this skill before installing. The Formsite operations themselves are clearly described and include user confirmation for writes and deletions, but do not run the documented remote installer commands unless you trust the OOMOL installer source and have a way to verify what will execute. Prefer an already installed, trusted oo CLI or a signed/version-pinned installation method.

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

External Script Fetching

High

Category: Supply Chain
Confidence: 98% confidence
Finding: The skill instructs users to install software by piping a remote script directly into a shell (curl ... | bash). If the install endpoint, transport path, or hosting account is compromised, arbitrary code would execute immediately on the user's machine with the user's privileges, turning a setup failure into a full client-side code execution risk.

Vague Triggers

Medium

Category: Not specified by scanner
Confidence: 96% confidence
Finding: The description says to use this skill for "ANY Formsite request" and "Whenever a task involves Formsite," which is extremely broad and overlaps with many ordinary requests involving Formsite. It does not provide trigger constraints, exclusions, or negative examples to clarify when the skill should or should not activate.
