# REDAXO CMS: editors can change live articles without approval permission

Link for people: https://infrastack.ai/live/CVE-2026-126318 (this .md is for agents)

REDAXO versions before 5.21.6 let an editor without the live-version permission change live article content by going around the working-version approval step. An attacker with a normal editor account can add, edit, delete, or reorder live content blocks, bypassing the approval workflow.

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

## How to check

- Check the installed REDAXO version in the project's `redaxo/src/core/boot.php` or the admin System page; versions below `5.21.6` are affected.
- Review which backend users hold the editor role without the `version[live_version]` permission.

## Fix

- REDAXO: upgrade to `5.21.6`

## From the sources

REDAXO before 5.21.6 contains an authorization bypass vulnerability that allows editors without the version[live_version] permission to modify live article versions by bypassing working version enforcement. Authenticated editors can add, edit, delete, toggle, or reorder live slices via content/functions, slice ids, content_slice_status, content_move_slice, history restore, or content_copy, bypassing approval workflows.
