Recruitee

Security checks for vulnerabilities and agentic risk

Overview

Recruitee actions have clear approval controls, but setup executes unverified downloads and may change other installed agent skills without sufficient disclosure.

Review and install a verified CLI release separately before using this skill. Consider disabling startup skill synchronization with OO_SKILLS_SYNC_DISABLED=1, as documented in the [CLI reference](https://github.com/oomol-lab/oo-cli/blob/main/docs/commands.md#environment-variables). Confirm that OOMOL may process your recruitment data and retain the required approval controls for changes. The bundled instructions were fully inspected, but the downloaded installer 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

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
95% confidence
Finding

The supplied chunk installs software from an external domain rather than performing Recruitee operations. Although installation can be a supporting implementation detail, nothing in the supplied content establishes this installer's relevance to the declared purpose. The downloaded script is not provided, so its further behavior cannot be assessed.

Content

No source excerpt is available for this finding.

External Script Fetching

High
Category
Supply Chain
Confidence
98% confidence
Finding

The curl-to-bash command immediately executes mutable remote content without pinning a version or verifying its integrity. HTTPS protects transport but does not prevent a compromised publisher or distribution endpoint from supplying malicious code; the missing-CLI condition reduces exposure but not the consequences.

Content

Scanner excerpt · SKILL.md (reported line 58)May include surrounding context.

The setup workflow executes downloaded installation scripts without warning the user about remote code execution.

Medium
Category
Output Handling
Confidence
95% confidence
Finding

The setup instructions direct the agent to execute downloaded shell or PowerShell code without an explicit approval gate or integrity verification. Although setup is conditional and the URLs belong to the CLI provider, a compromised distribution endpoint could execute arbitrary code with the invoking user's privileges.

No source excerpt is available for this finding.

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.
