CVE-2026-88826 Details
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.
A stored cross-site scripting vulnerability has been identified in the SmugMug Embed WordPress plugin, affecting versions through 3.13. The issue arises because the plugin's AJAX action for saving gallery data lacks proper authorization and cross-site request forgery (CSRF) protections. Additionally, the plugin fails to sanitize or escape the data before displaying it. This allows unauthenticated users to inject arbitrary web scripts that are executed when an administrator accesses the plugin's settings screen.
