Sol Devto Viral

Security checks for vulnerabilities and agentic risk

Overview

This skill openly targets dev.to growth automation, but it includes automated public publishing and a daily schedule without clear approval controls or safe secret handling.

Review carefully before installing. Only use this with a dedicated dev.to API key, confirm what account it can post to, require preview and explicit approval before each publish, and avoid any setup that embeds API keys in source code or creates an automatic launchd schedule without clear disable steps.

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
  • Trigger AbuseOverly Broad Trigger, Shadow Command Trigger, Keyword Baiting Trigger
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code

Vague Triggers

Confidence

Finding

The skill metadata describes a broad 'viral engine' for mining, advertising, and cross-posting content without clear invocation boundaries or user-approval gates. In an agent ecosystem, vague scope increases the chance the skill is selected for general content-growth requests and performs networked promotional or publishing actions the user did not explicitly intend.

Confidence

Finding

The skill explicitly includes a cross-post capability that publishes to dev.to via API, but the description does not prominently warn that it can perform external publication. Because the skill has HTTP posting permissions and is scheduled to run daily, this omission raises the risk of unintended public posting, spam-like behavior, or reputational damage if the agent uses it without informed user consent.

Missing User Warnings

Low
Category
Not specified by scanner
Confidence
88% confidence
Finding

The setup instructions disclose credential locations and state that the dev.to API key is embedded in the script, without any safety guidance. Embedding API keys in code and documenting secret paths can normalize insecure secret handling, increasing the chance of credential leakage, accidental commits, unauthorized publishing, or abuse of connected accounts.
