Publora Telegram

Security checks for vulnerabilities and agentic risk

Overview

This documentation-only skill helps publish user-chosen Telegram posts through Publora and shows no hidden installation, persistence, or unrelated data access.

Before installing, understand that using this skill involves sending post text, scheduling details, and selected media to Publora, and requires a Publora API key plus a Telegram bot with posting permission for the target channel or group.

  • 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
