## Affected

- Unknown Live Composer: fixed in 2.1.24

## Description

The Live Composer WordPress plugin before 2.1.24 does not sanitise and escape some of its Button module settings before outputting them on the front end, 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).

## Check your systems with an agent

```text
Check whether my systems are affected by CVE-2025-15714 (Live Composer < 2.1.24 - Admin+ Stored XSS via Button), using the cve.now data below.

Rules: work read-only. Do not run exploit code, proof-of-concept scripts or scanners that send attack payloads, and do not change any configuration, package, image or deployment. Report findings only.

What cve.now has for CVE-2025-15714 (entry last updated 2026-11-11):
Affected:
- Unknown Live Composer: fixed in 2.1.24
Fixed versions: 2.1.24.
Setup: unknown whether the bug needs a non-default feature or setting. Check the advisory.
CISA KEV: CVE-2025-15714 is not listed as of cve.now's last read.
This KEV status is for CVE-2025-15714 only. If you also check another CVE, look up its own KEV status; never assume it from this one.

How to check:
- Installed software: check what is actually running, not what a repo declares. Read the version from each host, container image and Kubernetes node (the binary's version output, the OS package database, image layers), and check whether the conditions above hold there. Distribution packages may carry a backported fix under an older version number; confirm against the distribution's own advisory.

Verify against the linked advisories before concluding, and cite the date you read each one:
- the references on https://cve.now/CVE-2025-15714
Do not conclude an asset is unaffected unless you checked it and the evidence covers both its version and the conditions above. If you could not check something, mark it unknown and say what is missing.

Report a table with one row per asset and these columns: Asset | Version or build | Status (affected, fixed, not applicable, unknown) | Compensating controls | Exposure (internet-facing, internal, none) | Evidence | Next action.
