Description
The bSlider plugin for WordPress is vulnerable to Stored Cross-Site Scripting via ACF field values shown on post sliders in versions 2.0.17 up to, and including, 2.2.2. The plugin does not sanitize field values and URLs before returning them, and the front-end script renders any value that contains HTML as raw markup. This makes it possible for authenticated attackers, with author-level access and above, to store arbitrary web scripts in the custom field values of their published posts. The scripts run whenever a user opens a page with a slider that displays those fields.
