Missing Authorization vulnerability in Fullworks Quick Paypal Payments allows Exploiting Incorrectly Configured Access Control Security Levels.This issue affects Quick Paypal Payments: from n/a through 5.7.25.

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 Quick Paypal Payments WordPress plugin before 5.7.26.4 does not sanitise and escape some of its settings, which could allow high privilege users such as admin to perform Stored Cross-Site Scripting attacks even when the unfiltered_html capability is disallowed (for example in multisite setup)
