Security checks for vulnerabilities and agentic risk

Overview

The skill coherently documents cloud-based image enhancement, including authentication, image uploads, and local API-key storage.

Install only if you trust dLazy with the images you select and accept its processing charges. Review the pinned CLI package, protect the saved organization API key, and check the service's privacy and retention terms before uploading sensitive images.

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 (4)

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
99% confidence
Finding

The supplied code consists solely of a login command, which materially differs from the declared image-enhancement purpose. Although authentication could support an image service, the chunk provides no evidence connecting this login operation to image processing.

Content

No source excerpt is available for this finding.

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
99% confidence
Finding

The supplied code performs a login operation rather than image super-resolution. Nothing in the chunk connects this authentication step to an image-processing workflow or implements the declared functionality. The command alone does not establish credential theft or other malicious behavior.

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
97% confidence
Finding

Authentication could support an image-processing workflow, but the supplied code contains only an authentication setup command and no implementation of the declared image super-resolution functionality. There is no evidence in this chunk of credential exfiltration or other additional behavior.

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.
