# Live Composer WordPress plugin: staff settings allow stored cross-site scripting

Link for people: https://infrastack.ai/live/CVE-2025-15712 (this .md is for agents)

The Live Composer WordPress plugin before 2.1.24 does not sanitise or escape some staff member settings before printing them on pages. An administrator can store script that runs in other users' browsers, even where the unfiltered_html capability is disabled, such as multisite setups.

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

## How to check

- Check the installed Live Composer plugin version in the WordPress admin Plugins screen; versions below `2.1.24` are affected.
- Confirm whether the site runs multisite or restricts `unfiltered_html`, since that is where the sources say the flaw matters.

## Fix

- Live Composer plugin: move to `2.1.24` or later.

## Timeline

- 2026-11-11T06:25:39+00:00 nvd https://nvd.nist.gov/vuln/detail/CVE-2025-15712

## From the sources

The Live Composer  WordPress plugin before 2.1.24 does not sanitise and escape some of its staff member settings before outputting them in pages, which could allow high-privilege users such as administrators to perform Stored Cross-Site Scripting attacks even when the unfiltered_html capability is disallowed (e.g. in multisite setups).
