Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in Hakan Ozevin WP BASE Booking allows Stored XSS. This issue affects WP BASE Booking: from n/a through 5.0.0.

The WP BASE Booking of Appointments, Services and Events plugin for WordPress is vulnerable to unauthorized access of data due to a missing capability check on the export_db function in all versions up to, and including, 4.9.2. This makes it possible for authenticated attackers, with Subscriber-level access and above, to expose sensitive information from the database, such as the hashed administrator password.

The WP BASE Booking of Appointments, Services and Events plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the ‘status’ parameter in all versions up to, and including, 4.9.1 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link.

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.
