X(Twitter) Post Automation

Security checks for vulnerabilities and agentic risk

Overview

This skill clearly discloses X automation, but it can use a logged-in browser session to publish AI-generated public posts without a final user approval step.

Install only if you are comfortable with an agent using your active X browser session to research trends, generate opinionated posts, and publish them. Before using it, require the agent to show the final draft, account, and destination, and get explicit confirmation before posting.

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

Missing User Warnings

High

Confidence
97% confidence
Finding

The workflow directs the agent to compose and publish a tweet automatically, but does not require an explicit confirmation step immediately before posting. Because posting to X is an external side effect with reputational and operational consequences, automatic publication of AI-generated, intentionally opinionated content can lead to accidental, harmful, or unauthorized public statements.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
90% confidence
Finding

The activation text is broad enough to trigger on generic requests like posting to X or checking trends, without strong guardrails on scope, consent, or review. In a skill that can generate and publish public content, over-broad invocation increases the chance the agent performs unintended social-media actions or gathers external context when the user did not clearly authorize the full workflow.
