Security audit

Ringba

Security checks for vulnerabilities and agentic risk

Overview

The skill is mostly a coherent Ringba read-only connector, but its setup instructions tell users to execute mutable remote installer scripts directly.

Review the installer path before installing. Prefer installing the oo CLI through a signed or verified package, or download and inspect the installer before running it. The Ringba actions shown are read-only, but the setup command has local code-execution impact if the installer endpoint is compromised.

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 recommends installing the CLI via a remote script piped directly into bash, which executes code fetched over the network without prior verification or integrity checking. If the install endpoint, transport path, or hosting environment were compromised, a user following these instructions could execute arbitrary attacker-controlled code on their system.

Finding

The description uses an extremely broad activation condition: "Use this skill for ANY Ringba request." That lacks clear boundaries for when the skill should or should not activate, and no exclusion examples are provided to narrow scope.
