# Vvveb CMS: crafted form field names allow SQL injection by admins

Link for people: https://infrastack.ai/live/CVE-2026-126374 (this .md is for agents)

Vvveb, a PHP content management system, builds INSERT column names from unescaped form array keys, so backticks in those keys can change the SQL statement. An authenticated back-office user who can save products can use this to write into unexposed columns or break SQL statements.

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

## How to check

- Check the installed Vvveb version against the affected range through 1.0.8.6.
- Look for the `@KEYS(:each)` macro and the `admin/sql/mysqli/product.sql` and `admin_auth_token.sql` procedures in the codebase.

- [advisory] Third-party advisory: www.vulncheck.com https://www.vulncheck.com/advisories/vvveb-through-1.0.8.6-sql-injection-via-keys-each-array-keys

## From the sources

Vvveb through 1.0.8.6 contains an SQL injection vulnerability because the @KEYS(:each) macro emits PHP array keys as backtick-quoted INSERT column names without escaping, and several procedures in admin/sql/mysqli/product.sql and admin_auth_token.sql omit the @FILTER guard. Authenticated back-office users able to save products can submit product_<feature> POST array keys containing backticks to redirect bound values into unexposed columns or break SQL statements.
