Cross-Site Request Forgery (CSRF) vulnerability in David Marcucci Password Protect Plugin for WordPress allows Stored XSS.This issue affects Password Protect Plugin for WordPress: from n/a through 0.8.1.0.

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.

The Password Protected – Ultimate Plugin to Password Protect Your WordPress Content with Ease plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 2.6.6 via the API. This makes it possible for authenticated attackers, with subscriber access or higher, to extract post titles and content, thus bypassing the plugin's password protection.

The PPWP – Password Protect Pages plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 1.8.9 via API. This makes it possible for unauthenticated attackers to obtain post titles, IDs, slugs as well as other information including for password-protected posts.

The PPWP WordPress plugin before 1.8.6 does not validate and escape some of its shortcode attributes before outputting them back in the page, which could allow users with a role as low as contributor to perform Stored Cross-Site Scripting attacks which could be used against high privilege users such as admins.
