97%of all CVEs are less likely

Readycheck to confirm it

The LayerSlider plugin for WordPress is vulnerable to SQL Injection via the ls_get_popup_markup action in versions 7.9.11 and 7.10.0 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for unauthenticated attackers to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.

Impact

Authenticated attackers can execute arbitrary SQL queries, potentially extracting sensitive data or compromising the database.

Fix

Update LayerSlider plugin to version 7.10.1 or later.

How to confirm it

Send: GET {{BaseURL}}/wp-content/plugins/LayerSlider/assets/static/public/front.css
Positive when: contains ".ls-clearfix:before"
Send: @timeout: 10s
Positive when: duration>=6 and status_code == 200 and contains(body, "<script>")
