WordPress Photospace Gallery plugin cross-site scripting vulnerability

WordPress and WordPress plugin are both products of the WordPress Foundation. WordPress is a blogging platform developed using the PHP language. WordPress plugin is an application plugin. WordPress Photospace Gallery plugin 2.3.5 and its previous versions are vulnerable to cross-site scripting, which stems from insufficient input cleanup and output escaping, and the settings parameters saved via the update() function are vulnerable to stored cross-site scripting. An authenticated attacker could use the vulnerability to inject cross-site code and launch an XSS attack.
