# Xibo: authenticated users can edit or delete any layout's actions

Xibo is an open source digital signage platform whose web CMS lacks access-control checks on the PUT and DELETE /action/{id} endpoints. An authenticated user can modify or delete layout actions on any layout, not just their own.

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

## How to check

- Check the installed Xibo CMS version; the sources say versions before `4.4.3` are affected.
- Review which non-administrator users have edit or delete rights on layouts.

## Fix

- Upgrade the Xibo CMS to `4.4.3` or later.

## Timeline

- 2026-10-28T14:33:23+00:00 nvd https://nvd.nist.gov/vuln/detail/CVE-2026-52729

## From the sources

Xibo is an open source digital signage platform with a web content management system and Windows display player software. Prior to 4.4.3, missing access-control checks on `PUT/DELETE /action/{id}` allow an authenticated user to modify or delete actions on any Layout. Exploitation requires the privilege to allow edits, including deletion, to all created Layouts, which is granted to non-administrators as standard. This issue concerns `Layout actions` rather than the separately reported DataSet export vulnerability. This issue is fixed in version 4.4.3.
