Original description
The Social Media Share Buttons & Social Sharing Icons plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via URL in all versions up to, and including, 3.0.1 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. Exploitation requires the victim to be on a mobile user-agent and to click the WeChat share icon, though once the dialog opens, script execution is automatic and requires no further user interaction.
