AI Analysis

Impact

The SH Email Alert plugin for WordPress is vulnerable to Reflected Cross‑Site Scripting through the 'mid' query parameter. The plugin does not properly sanitize user input or escape output before rendering it, allowing unauthenticated users to inject arbitrary web scripts that execute when a victim visits a crafted URL.
