What is CVE-2026-19723?

The Social Media Share Buttons & Social Sharing Icons plugin for WordPress, prior to version 3.0.1, contains a security flaw where it fails to properly escape user input. This weakness allows attackers to execute reflected cross-site scripting (XSS) attacks by injecting malicious scripts via an inline JavaScript event handler. The vulnerability is triggered when users interact with affected buttons, specifically in scenarios where the plugin is operating under a non-default icon display configuration.
