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 Scriptsez.net Virtual Calendar allow remote attackers to inject arbitrary web script or HTML via the (1) t and (2) yr parameters, and the (3) sho parameter when the m parameter is outside the intended range.

Virtual Calendar stores sensitive information under the web root with insufficient access control, which allows remote attackers to download an encoded password via a direct request for pwd.txt.
