Name of the Vulnerable Software and Affected Versions The Ultimate Before After Image Slider & Gallery versions prior to 4.7.19

Description The plugin fails to properly escape the after-label value of the slider. This allows users with the Author role or higher to store a malicious payload that is subsequently re-injected into the Document Object Model (DOM) by a bundled client-side script. This can lead to the execution of arbitrary code in the browser of any user, including administrators, who views the affected slider.

Recommendations Update The Ultimate Before After Image Slider & Gallery to version 4.7.19 or later.
