Sassy social share < 3.3.63 Admin+ Stored Cross-Site scripting

Description The plugin does not sanitise and escape some of its settings, which could allow high privilege users such as admin to perform Stored Cross-Site Scripting attacks even when the unfiltered_html capability is disallowed (for example in multisite setup)

PoC

1. Go to the plugin’s settings. 2. Change “Right offset” field to: 123;alert(1);// 3. Save settings.
