CVE-2026-14844 Details
Description
The Master Slider WordPress plugin through 3.11.2 does not sanitise and escape some of its shortcode attributes before outputting them in an inline script context, which could allow users with the Contributor role and above to perform Stored Cross-Site Scripting attacks that execute when the affected post is viewed. No fixed version is available. Until one ships, restrict the Contributor role to trusted users, or deactivate the Master Slider WordPress plugin through 3.11.2. Site owners who need to keep it active can block the ms_slider shortcode for roles below Editor, for example with a shortcode-restriction Master Slider WordPress plugin through 3.11.2, which prevents the attack without removing the Master Slider WordPress plugin through 3.11.2.
A stored cross-site scripting vulnerability has been identified in the Master Slider WordPress plugin, affecting versions through 3.11.2. The issue arises because the plugin fails to properly sanitize and escape certain shortcode attributes before rendering them in an inline script context. This flaw enables users with Contributor roles and above to execute scripts that are triggered when the affected post is viewed.
No official fix is available for this vulnerability. Users can deactivate the Master Slider WordPress plugin or restrict the Contributor role to trusted users. If the plugin must remain active, site owners can block the 'ms_slider' shortcode for roles below Editor using a shortcode-restriction plugin.
