Wisburg

Security checks for vulnerabilities and agentic risk

Overview

The skill mostly matches its Wisburg search/read purpose, but its setup includes direct execution of remote installer scripts and broad routing for all Wisburg requests.

Review the OOMOL CLI installation path before installing. Prefer a verified package, pinned release, checksum/signature validation, or manual inspection of the installer instead of allowing pipe-to-shell setup. Only connect the skill if you are comfortable with OOMOL-mediated access to your Wisburg account data.

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

External Script Fetching

High
Category
Supply Chain
Confidence
98% confidence
Finding

The skill includes a shell pipeline that downloads a remote script and executes it directly with bash. This pattern is dangerous because it gives full code-execution trust to content fetched at runtime; if the remote host, transport, CDN, or installer is compromised, the user may execute arbitrary attacker-controlled code.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
97% confidence
Finding

The trigger text instructs the agent to use this skill for ANY Wisburg-related request and instead of calling the API directly, which is broader than necessary and can force tool use in situations where a simpler or safer path would suffice. Overly broad routing increases the chance of unintended invocation, unnecessary credentialed access, and expanded blast radius if the skill behavior or downstream connector is flawed.
