## Description

The Better Payment plugin for WordPress is vulnerable to Sensitive Information Exposure via password-protected campaigns in all versions up to, and including, 2.4.2, due to the single campaign template, the [bp_campaign] shortcode and the campaign block rendering a campaign without checking whether it is password protected. This makes it possible for unauthenticated attackers to view the full content, figures and Donate button of password-protected campaigns without knowing the password.
