文本生成 Qwen 3.8 Max

Security checks for vulnerabilities and agentic risk

Overview

The verdict is benign because the scanners report no confirmed harmful behavior, though they flag a mismatch between the skill’s described Qwen capabilities and its authentication and CLI setup instructions.

The verdict is benign with medium confidence, not a guarantee of safety. Before installing, consider that the skill’s described model capabilities are not demonstrated by the supplied content, that its CLI package behavior was not established by the scan, and that some references could not be resolved.

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
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • MCP Tool PoisoningHidden Instructions, Unicode Deception, Parameter Description Injection
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code
Findings (7)

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
99% confidence
Finding

The supplied code only sets an authentication credential. It contains no model invocation, input handling, or connection to Qwen that would establish this as a supporting implementation detail of the declared functionality.

Content

No source excerpt is available for this finding.

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
99% confidence
Finding

The supplied code only configures CLI authentication; it does not invoke Qwen, process text or images, or perform reasoning. Authentication could support a model integration, but no such integration is present in this chunk. There is no evidence of credential exfiltration.

Content

No source excerpt is available for this finding.

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
98% confidence
Finding

The only supplied behavior is a CLI login command, which is materially different from the declared model functionality. Nothing in the chunk establishes that this login is a supporting implementation step for accessing Qwen. The command's specific authentication mechanism and downstream effects cannot be determined from this snippet.

No source excerpt is available for this finding.

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
96% confidence
Finding

The only supplied behavior is a login command, which is materially different from the declared model capabilities. Nothing in the chunk connects this authentication operation to the described model service or establishes it as a supporting implementation detail. The command's authentication mechanism and effects cannot be determined from this snippet.

Content

No source excerpt is available for this finding.

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
96% confidence
Finding

The description presents a reasoning model, while the supplied content is a generic external CLI invocation with no visible connection to Qwen. This is a material description-behavior mismatch, although the package's downstream behavior cannot be determined from this chunk alone.

Content

No source excerpt is available for this finding.

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
96% confidence
Finding

The supplied chunk is a generic external CLI invocation rather than an implementation of the described model capabilities. Although a CLI could support model access, neither the command nor any integration establishing that relationship is provided. The package's downstream behavior cannot be determined from this snippet, so no additional capabilities or malicious behavior are inferred.

Content

No source excerpt is available for this finding.

Whitespace Padding

Medium
Category
Prompt Injection
Confidence
70% confidence
Finding

Large whitespace padding was detected (a block of blank lines or a long run of spaces). This can push injected instructions below or to the right of the visible area so a human reviewer never sees them while the agent still reads them. Manual review of the hidden content is recommended.
