CVE-2026-4290

The WP Travel Pro plugin for WordPress lets anyone delete any user account, including administrators, through a REST API endpoint. The flaw exists in all versions up to 10.6.0 because the permission check always returns true and the user ID is passed directly to the delete function. Attackers can exploit this without authentication.
