Description

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.

Affected WordPress components

A confirmed match is backed by the plugin or theme slug. A possible match is based on the product name only and should be verified.
