OSV

Security checks for vulnerabilities and agentic risk

Overview

This skill is a coherent OSV lookup helper, with a notable but disclosed CLI installer risk users should handle carefully.

Install only if you want OSV queries routed through OOMOL's oo CLI. Treat the first-time installer commands as privileged software installation: verify the OOMOL CLI source and prefer safer install guidance where possible.

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

Finding

The skill instructs users to install software by piping a remotely fetched script directly into a shell (curl ... | bash). This is dangerous because any compromise of the remote host, transport, installer path, or publishing pipeline could lead to arbitrary code execution on the user's machine, and the skill context makes it more dangerous because it presents the command as an operational recovery step users may run verbatim.

Finding

The description says to use this skill for "ANY OSV request" and "Whenever a task involves OSV," which is a very broad activation condition for a markdown skill file. It does not provide narrower trigger boundaries, exclusions, or negative examples, so ordinary references to OSV could incorrectly invoke the skill.
