Moorcheh

Security checks for vulnerabilities and agentic risk

Overview

Moorcheh operations have clear safeguards, but missing-CLI setup directs the agent to execute downloaded code without separate installation approval.

Review setup before enabling this skill. Install the CLI through a separately approved process with verified provenance, and require approval before executing downloaded installers. Expect Moorcheh requests to pass through OOMOL, and retain the documented confirmation requirements for writes and deletions. The external installer and backend were not verified; no malicious behavior was established in the bundled artifact.

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

  • Output HandlingUnvalidated Output Injection, Cross-Context Output, Unbounded Output

Findings (5)

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
97% confidence
Finding

The supplied command performs remote installer execution, not Moorcheh data operations. Nothing in the supplied content establishes that this installer is a supporting dependency for Moorcheh. The downloaded script's contents are unavailable, so its further behavior cannot be determined.

Content

No source excerpt is available for this finding.

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
83% confidence
Finding

The only supplied behavior is oo auth login. Nothing in the chunk connects that CLI or its authentication target to Moorcheh. Authentication could be a supporting implementation detail if such a connection were established, but the supplied content instead presents a materially different, login-only purpose.

External Script Fetching

High
Category
Supply Chain
Confidence
98% confidence
Finding

The curl-to-bash pipeline immediately executes whatever script the remote endpoint currently serves, without version pinning or independent integrity verification. Compromise of the distribution endpoint or release infrastructure could yield arbitrary code execution with the invoking user's privileges, potentially exposing local files and credentials; HTTPS alone does not prevent that scenario.

The setup workflow executes downloaded installer scripts without warning about remote code execution or system changes.

Medium
Category
Output Handling
Confidence
94% confidence
Finding

The fallback setup directs execution of downloaded shell or PowerShell code without an explicit installation approval step or explanation of host changes. Although installation is relevant and conditional, a missing CLI can expand a routine data request into host-level code execution; the declared Bash tool restriction may limit execution in some environments but is not a substitute for safe setup guidance.

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.
