# Firelight Lightbox WordPress plugin: image attributes let contributors inject scripts

The Firelight Lightbox WordPress plugin before 2.3.24 does not escape image attribute values before the browser processes them. A contributor-level user can inject scripts that run in the browser of anyone who views or previews the affected content.

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

## How to check

- Check the installed Firelight Lightbox plugin version in the WordPress admin plugins list or `wp plugin get firelight-lightbox --field=version` (the slug is unknown from the sources).
- Confirm whether contributor-level or higher accounts can create or edit posts that use the plugin.

## Fix

- Firelight Lightbox plugin: move to `2.3.24` or later.

## Timeline

- 2026-10-31T06:33:50+00:00 nvd https://nvd.nist.gov/vuln/detail/CVE-2026-118438

## From the sources

The Firelight Lightbox WordPress plugin before 2.3.24 does not properly escape image attribute values before processing them in the browser, which could allow users with contributor-level access and above to inject arbitrary web scripts that execute when another user views or previews the affected content.
