Improper Neutralization of Input During Web Page Generation (XSS or 'Cross-site Scripting') vulnerability in BannerSky BSK Forms Blacklist allows Reflected XSS.This issue affects BSK Forms Blacklist: from n/a through 3.8.
The BSK Forms Blacklist WordPress plugin before 3.7 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 unfilteredhtml capability is disallowed (for example in multisite setup).
