SmartRecruiters

Security checks for vulnerabilities and agentic risk

Overview

The SmartRecruiters functions fit the stated purpose, but setup can execute unchecked remote installers and introduce broader agent changes without clear user control.

Review setup before installing. Use a reviewed, pinned CLI release and require approval for software installation or changes to other agent skills. Consider disabling the CLI's automatic skill synchronization. OOMOL will mediate access to recruitment data; the remote installers and hosted connector implementation were not verified.

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
Vulnerability Patterns
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code
  • Excessive AgencyUnrestricted Tool Access, Autonomous Decision Making, Scope Creep
  • Output HandlingUnvalidated Output Injection, Cross-Context Output, Unbounded Output

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
98% confidence
Finding

The supplied command performs remote installer execution, not the declared SmartRecruiters data access. Nothing in the supplied chunk establishes that this installation is a supporting dependency for SmartRecruiters functionality. The downloaded script is not provided, so its additional behavior cannot be assessed.

External Script Fetching

High
Category
Supply Chain
Confidence
98% confidence
Finding

Piping an HTTPS response directly into bash executes mutable remote content without a pinned version or independent integrity check. Compromise of the distribution endpoint or its publishing pipeline could execute attacker-controlled code with the agent's local permissions; this is the same underlying installation risk highlighted by SQP-2, not evidence that the vendor is malicious.

The setup workflow executes downloaded installation scripts without warning about running remote code or modifying the local system.

Medium
Category
Output Handling
Confidence
96% confidence
Finding

The setup instructions direct the agent to execute downloaded shell or PowerShell code without an explicit approval checkpoint or integrity verification. Although setup is conditional on a missing CLI, this can turn a read-only data request into local code execution with the agent's permissions if installation is permitted by the runtime.

Autonomous Decision Making

Medium
Category
Excessive Agency
Confidence
80% confidence
Finding

Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.
