 "title": "Better Payment <= 2.4.2 - Authenticated (Author+) Missing Authorization to Campaign Creation and Modification via REST API",
 "description": "The Better Payment plugin for WordPress is vulnerable to unauthorized modification of data via the bp_campaign REST API endpoint in all versions up to, and including, 2.4.2, due to the bp_campaign post type being registered with show_in_rest while inheriting the default post capabilities instead of the manage_options requirement that the plugin's own campaign screens enforce. This makes it possible for authenticated attackers with Author-level access and above to create and publish campaigns through /wp/v2/bp_campaign. Users with Editor-level access can also edit, unpublish, password-protect or delete any campaign.",
