The Freemius SDK, as used by hundreds of WordPress plugin and theme developers, was vulnerable to Cross-Site Request Forgery and Information disclosure due to missing capability checks and nonce protection on the _get_debug_log, _get_db_option, and the _set_db_option functions in versions up to, and including 2.4.2. Any WordPress plugin or theme running a version of Freemius less than 2.4.3 is vulnerable.

Cross-site scripting (XSS) vulnerability in the Contact Form Clean and Simple (clean-and-simple-contact-form-by-meg-nicholas) plugin 4.4.0 and earlier for WordPress allows remote attackers to inject arbitrary web script or HTML via the cscf[name] parameter to contact-us/.
