Gitee

Security checks for vulnerabilities and agentic risk

Overview

The Gitee features fit the stated purpose, but setup can execute unverified remote installers without first obtaining your approval.

Review the setup behavior before installing. Install a reviewed CLI version yourself and require approval before the agent downloads or executes installers. Check which Gitee permissions you grant OOMOL and whether the CLI installs additional agent skills. The bundled skill contains no demonstrated malicious payload, but its remote installers could not be inspected. The clean static scan does not resolve that uncertainty.

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
  • MCP Tool PoisoningHidden Instructions, Unicode Deception, Parameter Description Injection
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
99% confidence
Finding

The supplied command runs a remote installer rather than searching or reading Gitee data. Nothing in the supplied chunk establishes that this installation is a supporting dependency for the declared functionality. The remote script's contents and effects are not available for assessment.

Content

No source excerpt is available for this finding.

External Script Fetching

High
Category
Supply Chain
Confidence
98% confidence
Finding

Piping a remotely fetched script directly into Bash executes mutable remote code with the agent process's privileges, without a pinned version or independent integrity verification. Compromise of the installer distribution path could enable credential theft or arbitrary local changes; HTTPS and the missing-CLI condition do not eliminate this supply-chain risk, and the PowerShell alternative has the same issue.

Content

The setup fallback instructs the agent to execute downloaded installation scripts without warning the user about local system changes.

Medium
Category
Output Handling
Confidence
95% confidence
Finding

The fallback directs the agent to install software when the CLI is missing without requiring user approval or explaining local system changes. A request to read Gitee data does not itself authorize installing software, and the setup context limits when this happens but does not establish consent.

Content

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.
