The Image Photo Gallery Final Tiles Grid WordPress plugin before 3.6.16 does not escape gallery lightbox configuration values before printing them into an inline script on every page that embeds the gallery, allowing users with contributor-level access and above to store JavaScript that executes in the browser of anyone who views the gallery, including administrators.
