WP Easy Pay <= 4.5.0 - Missing Authorization to Authenticated (Subscriber+) Arbitrary Post Status Modification via wpep_draft_confirm AJAX Action
The WP Easy Pay – Payment and Donation form Builder for Square plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 4.5.0. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for authenticated attackers, with subscriber-level access and above, to set the status of arbitrary posts and pages to 'draft', effectively unpublishing arbitrary site content.
Quick answer
WP Easy Pay – Payment and Donation form Builder for Square should be reviewed and updated if it matches the affected versions. The recommended fix is to apply the vendor-supported patched version or the mitigation steps below, then retest the public website with Fixnx.
