Description

Vito is a self-hosted web application that helps manage servers and deploy PHP applications into production servers. Prior to version 3.20.3, a missing authorization check in workflow site-creation actions allows an authenticated attacker with workflow write access in one project to create/manage sites on servers belonging to other projects by supplying a foreign server_id. This issue has been patched in version 3.20.3.
