# Live Composer WordPress plugin: stored XSS via pagination shortcode setting

Link for people: https://infrastack.ai/live/CVE-2026-119073 (this .md is for agents)

The Live Composer WordPress page builder plugin before 2.1.23 does not escape a pagination setting in its post-listing shortcodes when outputting it into an HTML attribute. A user with the Contributor role or higher can store a script that runs in other users' browsers.

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

## How to check

- Check the installed Live Composer version in the WordPress admin plugin list or the plugin header in `wp-content/plugins/live-composer-page-builder/`
- Look for post-listing shortcodes with a pagination attribute in post content, if the team can search the database
- Compare the installed version against `2.1.23`

## Fix

- Live Composer plugin: `2.1.23` (fixed in versions before 2.1.23 is the reported issue; upgrade to `2.1.23` or later)

## Timeline

- 2026-11-07T06:46:04+00:00 nvd https://nvd.nist.gov/vuln/detail/CVE-2026-119073

## From the sources

The Live Composer  WordPress plugin before 2.1.23 does not escape a pagination setting supplied through its post-listing module shortcodes before outputting it in an HTML attribute, allowing users with the Contributor role and above to perform Stored Cross-Site Scripting attacks.
