Short explanation

The SmugMug Embed WordPress plugin through 3.13 contains an unauthenticated stored XSS vulnerability via the saveSelectedAlbums AJAX action (S0). Unauthenticated users can store arbitrary web scripts that execute when an administrator views the settings screen (S0).

Why does it matter?

The lack of authorisation or CSRF checks and failure to sanitise data allows attackers to perform exploits targeting the plugin settings screen (S0).

What should be done?

  • Follow vendor advisories and check for updates from official sources (S0)

Show the technical text from the sources

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.
