description

Live Composer versions earlier than 2.1.23 are affected by stored cross-site scripting in post-listing shortcode pagination settings. An authenticated user with at least the WordPress Contributor role can cause browser-executed content to be stored and rendered.

mitigation

Upgrade Live Composer to version 2.1.23 or later. Restrict Contributor-or-higher access to trusted users until the update is complete.

fixed in 2.1.23
