HelloLeads

Security checks for vulnerabilities and agentic risk

Overview

The HelloLeads connector behavior is mostly coherent, but its setup instructions tell users to run unverified remote installer scripts directly.

Review the installer instructions before installing. Prefer an official, versioned, signed, or checksum-verified oo CLI installation method, and do not run the remote installer commands with elevated privileges unless OOMOL documents why that is required. For normal use, confirm any HelloLeads lead submission payload before allowing the write action.

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 instructs users to install software via curl ... | bash, which executes a remote script directly without verification. If the install endpoint, transport chain, or hosting account is compromised, arbitrary code could run on the user's machine with the user's privileges.

Finding

The description says to use this skill for "ANY HelloLeads request" and "Whenever a task involves HelloLeads," which is a very broad activation condition. This lacks clear trigger boundaries or exclusion conditions and could cause unintended invocation for loosely related mentions of HelloLeads.
