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.

Multiple cross-site scripting (XSS) vulnerabilities in payper/payper.php in the Pay Per Media Player plugin 1.24 and earlier for WordPress allow remote attackers to inject arbitrary web script or HTML via the (1) fcolor, (2) links, (3) stitle, (4) height, (5) width, (6) host, (7) bcolor, (8) msg, (9) id, or (10) size parameter.
