PingBell

Security checks for vulnerabilities and agentic risk

Overview

The skill is mostly coherent for operating PingBell through OOMOL, but its fallback setup tells the agent to execute remote installer scripts without verification.

Review the installer step before using this skill. Prefer installing the oo CLI from official, verifiable documentation or a package/release with checksum or signature verification. For normal use, confirm any ring_source payload because it changes PingBell state.

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

Finding

The skill instructs users to install software via curl ... | bash, which executes a remote script without prior verification. If the hosting endpoint, transport, or distribution pipeline is compromised, an attacker could achieve arbitrary code execution on the user's machine; placing this in a fallback setup section still makes it dangerous because the skill normalizes unsafe installation behavior.

Finding

The description says to use this skill for "ANY PingBell request" and "Whenever a task involves PingBell," which is an expansive activation condition that lacks clear boundaries or exclusions. For a markdown skill file, this is a vague trigger because it does not specify narrower contexts, example intents, or negative cases to prevent accidental invocation.
