SmugMug Embed <= 3.13 - Unauthenticated Stored XSS via saveSelectedAlbums
The SmugMug Embed WordPress plugin through 3.13 does not have authorisation or CSRF checks on an AJAX action that stores gallery data, and does not sanitise or escape that data before outputting it, allowing unauthenticated users to store arbitrary web scripts that execute when an administrator views the SmugMug Embed WordPress plugin through 3.13's settings screen.
