WHAT IT DOES

What vikunja_webhooks does on Vikunja MCP Server

RISK

Why vikunja_webhooks is rated Medium

Webhooks are configuration data that can be created, updated, and deleted. While webhook management is Write-category (reversible), the severity is high because misconfigured webhooks could expose sensitive task/project data to external services, create security vulnerabilities, or trigger unintended external actions.

From the tool's definition Tool description states "Manage webhooks for integrating Vikunja events with external services" — webhook management implies creating, updating, or configuring webhooks, which are reversible write operations that modify system integrations.
