The Social Media Share Buttons & Social Sharing Icons plugin for WordPress has a security issue that allows hackers to insert harmful code into certain pages, potentially causing harm to users. This vulnerability exists in all versions of the plugin up to 2.8.8 and is caused by a lack of proper protection against malicious input. This could be exploited by attackers with high-level access to the website to inject their own code that will run when a user views the affected page. Please note that this only affects certain types of WordPress setups.
