Summary

The Master Slider WordPress plugin through 3.11.2 does not sanitize and escape some shortcode attributes before outputting them in an inline script context, allowing users with Contributor role and above to perform Stored Cross-Site Scripting attacks that execute when the affected post is viewed.

Risk Assessment

An attacker with Contributor role or higher can inject malicious scripts that execute in the browser of administrators or other users viewing the post, potentially leading to session theft, account takeover, or further site compromise.

Recommendation

Until a fix is available, restrict the Contributor role to trusted users or deactivate the Master Slider plugin. If you need to keep it active, block the ms_slider shortcode for roles below Editor, for example with a shortcode-restriction plugin.

Original NVD description (English source)

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.
