Description

The FancyBox for WordPress plugin for WordPress is vulnerable to Stored Cross-Site Scripting via admin settings in versions 3.0.2 to 3.3.3 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with administrator-level permissions and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This only affects multi-site installations and installations where unfiltered_html has been disabled.

Affected products

• colorlibplugins FancyBox for WordPress: from 3.0.2 before 3.3.3 — fixed in 3.3.3

How to fix

Upgrade to a fixed version: colorlibplugins FancyBox for WordPress 3.3.3. Check the vendor advisory for mitigations.
