Name of the Vulnerable Software and Affected Versions FlexTable WordPress plugin versions prior to 3.19.2

Description The FlexTable WordPress plugin does not properly sanitise and escape imported links from Google Sheet cells. This could allow users with high privileges, such as administrators, to perform Stored Cross-Site Scripting (XSS) attacks. This is possible even when the unfiltered html capability is disabled, for example, in a multisite setup.

Recommendations Update the FlexTable WordPress plugin to version 3.19.2 or later.
