Description:

The Html Social share buttons plugin for WordPress is susceptible to Stored Cross-Site Scripting through the plugin’s `zm sh btn` shortcode. Insufficient input sanitization and output escaping on user-supplied attributes allows authenticated attackers with contributor-level access or higher to inject arbitrary web scripts into pages.
