The Prisna GWT WordPress plugin before 1.4.14 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).

The Prisna GWT – Google Website Translator plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 1.4.11 via deserialization of untrusted input from the 'prisna_import' parameter. This makes it possible for authenticated attackers, with Administrator-level access and above, to inject a PHP Object. No known POP chain is present in the vulnerable software. If a POP chain is present via an additional plugin or theme installed on the target system, it could allow the attacker to delete arbitrary files, retrieve sensitive data, or execute code.
