CVE-2026-29789Public exploitNetwork attack vector

Cross-project server modification via unchecked workflow target

Published Mar 6, 2026 · Updated Mar 6, 2026

Missing authorization in Vito before 3.20.3 allows remote authenticated users to create sites on servers in other projects. App\WorkflowActions\Site\CreateSite::run loads an arbitrary server_id and invokes site creation without enforcing the target server's project policy. Project admin or owner access, workflow write permission, and a known or guessed foreign server ID are required; successful requests dispatch installation jobs that modify the victim server.
