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.

Unauthenticated Cross Site Request Forgery (CSRF) in Post Views Counter <= 1.4.4 versions.

The Post Views Count WordPress plugin through 3.0.2 does not validate and escape some of its shortcode attributes before outputting them back in a page/post where the shortcode is embed, which could allow users with the contributor role and above to perform Stored Cross-Site Scripting attacks

The Post Views Counter WordPress plugin before 1.3.5 does not sanitise or escape its Post Views Label settings, which could allow high privilege users to perform Cross-Site Scripting attacks in the frontend even when the unfiltered_html capability is disallowed
