Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in Kiran Potphode Easy Charts allows DOM-Based XSS. This issue affects Easy Charts: from n/a through 1.2.3.

The iChart – Easy Charts and Graphs plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘width’ parameter in all versions up to, and including, 2.1.0 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

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.
