Name of the Vulnerable Software and Affected Versions:
Social Share Buttons for WordPress versions 2.7 and earlier
Description:
The issue allows high privilege users, such as admins, to perform Stored Cross-Site Scripting attacks, even when the unfiltered html capability is disallowed, for example, in a multisite setup. This is due to the plugin not sanitizing and escaping some of its settings.
Recommendations:
Social Share Buttons for WordPress versions 2.7 and earlier: Update the plugin to a version that sanitizes and escapes its settings to prevent Stored Cross-Site Scripting attacks.
