LayerSlider Plugin 7.9.11 – 7.10.0 – Unauthenticated SQL Injection
Plugin slug: LayerSlider
Update to version: 7.10.1
The breach can be done trough the ls_get_popup_markup action 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 hackers to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.
