Security checks for vulnerabilities and agentic risk

Overview

The skill coherently supports cloud-based video creation and clearly discloses authentication, project access, file uploads, and saved sessions.

Prompts and selected attachments go to dLazy, and video generation may consume paid credits. Choose the intended organization project, upload only appropriate media, and protect or revoke the saved API key as needed. This review does not establish the security of the external CLI or hosted service.

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 code only lists organization projects; it does not perform any declared video-generation or assembly steps. No connection is shown between this project enumeration and the stated video-making purpose, making the observed behavior materially different from the description.

Content

No source excerpt is available for this finding.

MCP Tool Poisoning
Confidence
99% confidence
Finding

The supplied code only enumerates organization projects; it does not perform any declared video-production step. No connection is shown between this project listing and the video-making workflow, so the observed behavior materially differs from the declared purpose.

Category
MCP Tool Poisoning
Confidence
96% confidence
Finding

Authentication could support a video-making workflow, but the supplied chunk contains only credential setup and no implementation or invocation of the advertised video-making capabilities. Its demonstrated purpose therefore materially differs from the description. There is no evidence here of credential theft or video output.

MCP Tool Poisoning
Confidence
90% confidence
Finding

Login could support a larger video workflow, but it is the entirety of the supplied code and has no demonstrated connection to the declared production capabilities. As supplied, the code does not substantiate the described purpose. There is no evidence here of credential theft or other malicious behavior.

MCP Tool Poisoning
Confidence
86% confidence
Finding

No storyboard creation, media generation, voiceover, subtitle rendering, or video assembly is present. Login could support a larger video-making workflow, but the supplied code contains only that operation and establishes no connection to the advertised functionality. The command alone does not demonstrate credential theft or other malicious 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.
