clawec-ozon-product-search

Security checks for vulnerabilities and agentic risk

Overview

This skill is a straightforward Ozon product-search helper that sends user-provided keywords to the disclosed ClawEC API using a user-supplied API key.

Install only if you are comfortable sending searched keywords to ClawEC and using a ClawEC API key from your environment. Do not put secrets in commands or files, and review ClawEC's service terms and data handling if the keywords reveal sensitive business plans.

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
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • MCP Least PrivilegeUnderdeclared Capability, Wildcard Permission, Missing Permission Declaration
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code
Findings (7)

Undeclared Tool Scope

Medium
Category
MCP Least Privilege
Confidence
89% confidence
Finding

The skill demonstrates shell execution via curl/bash but does not declare any tool scope or allowed-tools restrictions. This increases the attack surface because an agent may invoke shell unexpectedly or more broadly than intended, making command execution harder to govern and audit.

External Transmission

Medium
Category
Data Exfiltration
Confidence
60% confidence
Finding

Data is being sent to an external URL. This could be legitimate telemetry or data exfiltration. Manual review is recommended.

Missing User Warnings

Medium
Category
Not specified by scanner
Confidence
90% confidence
Finding

This code performs an HTTP POST and attaches a bearer token from the CLAWEC_API_KEY environment variable, but the script provides no visible notice, logging, or comment explaining that it will transmit data to an external service using credentials. For code files, outbound network calls and credential usage should have some user disclosure unless clearly documented elsewhere, which is not evident in this file.

Natural-Language Policy Violations

Low
Category
Not specified by scanner
Confidence
96% confidence
Finding

The markdown states '默认中文摘要' (default Chinese summary), which imposes a language preference in the skill behavior. Under the policy, language constraints should either be user-selectable or clearly justified as region-specific; this file does not provide such an opt-in or justification.

Natural-Language Policy Violations

Low
Category
Not specified by scanner
Confidence
84% confidence
Finding

This markdown file is natural-language documentation, and all headings and field descriptions are presented only in Chinese. Under the policy, forcing a specific language without user opt-in can be a language/locale policy violation when no justification or alternative is provided.

Natural-Language Policy Violations

Low
Category
Not specified by scanner
Confidence
97% confidence
Finding

The usage and environment-variable error messages are hard-coded in Chinese, which imposes a specific language on all users. The policy allows locale constraints only when users can opt in or when the restriction is clearly documented and justified, neither of which is shown here.
