Security checks for vulnerabilities and agentic risk

Overview

The skill’s hosted document-to-video workflow is coherent and clearly discloses file uploads, account authentication, and saved sessions.

Only attach documents you are comfortable sending to dLazy. Check its retention terms and credit costs, protect the saved organization API key, and revoke it when no longer needed.

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

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
99% confidence
Finding

The supplied command queries organization project metadata rather than processing a PDF or producing a video. No connection to the declared workflow is shown, so this is an undeclared capability and a materially different purpose.

No source excerpt is available for this finding.

MCP Tool Poisoning
Confidence
99% confidence
Finding

The supplied code only lists organization projects. It contains no PDF processing or video-generation steps, and no context establishes project enumeration as a supporting implementation detail of the declared workflow.

MCP Tool Poisoning
Confidence
97% confidence
Finding

The supplied code performs only a login operation, which materially differs from the declared conversion workflow. Authentication could support a larger implementation, but the provided chunk establishes no such relationship. There is no evidence here of credential theft or other additional behavior.

MCP Tool Poisoning
Confidence
97% confidence
Finding

The supplied code contains only a login command and performs none of the declared PDF-to-video steps. No context establishes this login as a supporting dependency of the advertised workflow. The command alone does not establish what credentials, services, or resources it accesses.

MCP Tool Poisoning
Confidence
92% confidence
Finding

Authentication could support a video-generation workflow, but the supplied chunk contains no PDF processing or video-generation operations and does not establish such a connection. Its sole demonstrated behavior is credential configuration, which does not substantiate the declared primary purpose. No credential exfiltration or other malicious behavior is shown.

Confidence

Finding

The supplied chunk performs only authentication configuration; it contains none of the declared PDF-to-video workflow. Authentication could support such a workflow, but the provided code does not establish that connection. There is no evidence here of PDF access, video generation, or credential exfiltration.

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.
