CVE-2026-29789 | Vito: Cross-project privilege escalation in workflow site-creation actions allows unauthorized server modification

Exp

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.

Base score Version Severity Vector Exploitability Impact Score source
9.9 3.1 CRITICAL
CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H Click to expand
Attack vector (AV:N)
Could be attacked over the internet or any normal routed network—not just someone sitting at the machine.
Attack complexity (AC:L)
Once they can reach the bug, pulling it off is straightforward—no weird race conditions or rare setup.
Privileges required (PR:L)
A normal user session is enough; they don’t have to be admin.
User interaction (UI:N)
Nobody has to click “OK” or open a trap file; it can work without a victim helping.
Scope (S:C)
Breaking this can reach past the original component and bite other resources—bigger blast radius.
Confidentiality (C:H)
Serious risk that confidential data gets exposed in a big way.
Integrity (I:H)
They could widely tamper with or forge data—trust in the data is badly hurt.
Availability (A:H)
Could take the service down hard or make it unusable for people who depend on it.
