Name of the Vulnerable Software and Affected Versions The Simple Social Media Share Buttons – Social Sharing for Everyone WordPress plugin versions prior to 3.2.3

Description The issue concerns the SSB shortcode in the plugin, where the align and like button size parameters are not properly escaped. This could allow users with a role as low as Contributor to perform Stored Cross-Site Scripting attacks.

Recommendations For versions prior to 3.2.3, update to version 3.2.3 or later to resolve the issue. As a temporary workaround, consider restricting the use of the SSB shortcode or limiting the roles that can use it to prevent exploitation.
