The Starbox WordPress plugin before 3.5.2 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).

The Starbox WordPress plugin before 3.5.0 does not sanitise and escape some parameters, which could allow users with a role as low as Contributor to perform Cross-Site Scripting attacks

The Starbox plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the Job Settings user profile fields in all versions up to, and including, 3.4.8 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with subscriber-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
