# Vvveb: cross-site GET requests let attackers change admin data

Link for people: https://infrastack.ai/live/CVE-2026-126323 (this .md is for agents)

Vvveb is a content management system whose admin CSRF check only validates tokens on POST requests, so GET requests are not protected. A lured logged-in admin who opens a malicious page can have accounts, sites, orders, menus or comment status changed or deleted.

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

## Affected

- vendor:Vvveb affected range not listed fixed no fixed version listed

## How to check

- Check the installed Vvveb version against the range in the advisory: `1.0.8.6` and earlier are affected.
- Look at `admin/controller/base.php` for the `checkCsrf()` function and whether it validates tokens for GET requests as well as POST.

## Documents

- [advisory] Vendor advisory: github.com https://github.com/givanz/Vvveb/security/advisories/GHSA-grxp-rj92-j8xr
- [advisory] Third-party advisory: www.vulncheck.com https://www.vulncheck.com/advisories/vvveb-through-1.0.8.6-csrf-via-get-admin-state-changing-actions

## From the sources

Vvveb through 1.0.8.6 contains a cross-site request forgery vulnerability that allows attackers to perform admin state-changing actions because checkCsrf() in admin/controller/base.php only validates tokens for POST requests. Attackers can lure a logged-in admin into loading a forged cross-site GET request to delete admin/user accounts, sites, orders, and menus or change comment status.
