Linkup

Security checks for vulnerabilities and agentic risk

Overview

The skill mostly matches its Linkup search purpose, but its setup instructions include running a mutable remote installer directly in the shell.

Review the OOMOL CLI installation path before installing. Prefer installing from official, versioned, signed or checksum-verified releases, and do not let an agent run the curl|bash or irm|iex installer automatically. Also avoid sending secrets or unrelated private data in Linkup connector payloads.

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: 96% confidence
Finding: The skill instructs the agent to install software by piping a remotely fetched script directly into bash, which is a classic unsafe pattern. If the install server, TLS trust chain, DNS resolution, or hosting account is compromised, arbitrary code would execute immediately on the user's machine with the agent's privileges, and the skill context explicitly encourages doing this as part of setup.
