# Vvveb CMS: site admin can save PHP through code editor, running commands

Link for people: https://infrastack.ai/live/CVE-2026-126370 (this .md is for agents)

Vvveb through 1.0.8.6 lets a restricted site_admin role inject PHP by saving .sql files in the admin code editor, using an @IF macro payload that bypasses extension and content deny-lists. The injected code runs when the model loads, giving the attacker OS command execution as the web server user.

_Summary, check and fix written by a model from the sources; labelled as such._

## Affected

- composer:Vvveb affected <= 1.0.8.6 fixed no fixed version listed

## How to check

Check the installed Vvveb version (<= 1.0.8.6 is affected; no fixed release listed). List who holds the site_admin role. Look in plugins/*/sql/*/*.sql for lines starting with @IF whose condition holds PHP calls (file_put_contents, shell_exec, system), and in storage/model/ for generated models containing them.

## Fix

No patched version as of the 2026-10-29 GitHub advisory (patched versions: None). Until one ships, restrict the site_admin role and the admin code editor.

## From the sources

Vvveb through 1.0.8.6 contains a remote code execution vulnerability allowing restricted site_admin roles to inject PHP by saving .sql files through the admin code editor. Attackers can bypass extension and content deny-lists with an @IF macro payload that compiles into executable PHP when the model loads, running OS commands as the web user.
