Authenticated administrator escalation via unchecked role submission

Published Aug 23, 2021 · Updated Aug 3, 2024

Privilege escalation in Hossni Mubarak HM Multiple Roles before 1.3 allows remote authenticated users to assign themselves administrator access. The profile-update handler trusts submitted role checkboxes even though the interface only disables them for non-administrators, so a tampered request persists an administrator role. Any low-privileged WordPress account can submit its own profile form and gain full site administration.
