CVE-2026-18053
MemberDash <= 1.8.7 - Authenticated (Subscriber+) Privilege Escalation to Administrator via Edit Profile 'id' Parameter
Published Nov 14, 2026
CVSS 3.1 · 8.8 High
EPSS n/a
KEV · Not listed
Description
The MemberDash plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 1.8.7. This is due to a mass-assignment vulnerability in the `user_account_manager()` function's edit_profile branch, where all submitted `$_POST` fields are iterated and directly assigned to the current member object via the `MS_Model` `__set()` magic method with no field allowlist and no capability or ownership check on the submitted `id` parameter. This makes it possible for authenticated attackers, with subscriber-level access and above, to inject an arbitrary user ID via the `id` parameter — overwriting any WordPress user's email address and password, including the site administrator's — and subsequently use those modified credentials to gain full administrative access to the site.
