Several plugins for WordPress hosted on WordPress.org have been compromised and injected with malicious PHP scripts. A malicious threat actor compromised the source code of various plugins and injected code that exfiltrates database credentials and is used to create new, malicious, administrator users and send that data back to a server. Currently, not all plugins have been patched and we strongly recommend uninstalling the plugins for the time being and running a complete malware scan.

The Social Sharing Plugin – Social Warfare plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'socialWarfare' shortcode in all versions up to, and including, 4.4.6.1 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers with contributor-level and above permissions to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

The Social Warfare plugin for WordPress is vulnerable to Remote Code Execution in versions up to, and including, 3.5.2 via the 'swp_url' parameter. This allows attackers to execute code on the server.

The Social Warfare plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 4.4.0.

The Social Warfare plugin for WordPress is vulnerable to authorization bypass due to a missing capability check on several AJAX actions in versions up to, and including, 4.3.0.
