WordPress · Wp Maps Pro · CVE-2026-8732
**Name of the Vulnerable Software and Affected Versions**
WP Maps Pro versions prior to 6.1.1
**Description**
An unauthenticated privilege escalation flaw exists in the WP Maps Pro plugin, which is used by over 15,000 websites. The issue stems from a temporary access feature designed for support troubleshooting. The AJAX action `wpgmp temp access ajax` is registered for unauthenticated users and relies on a nonce check using `fc-call-nonce`. However, this nonce is publicly embedded in the frontend JavaScript object `wpgmp local`, making the check ineffective. An attacker can invoke the `wpgmp temp access support()` handler with the parameter `check temp=false` to unconditionally create a new WordPress user with administrator privileges via `wp insert user()`. The system then returns a magic login URL that uses `wp set auth cookie()` to authenticate the attacker as the new administrator, leading to complete site takeover. This flaw has been actively exploited in the wild, with thousands of attacks blocked by security services in single-day periods.
**Recommendations**
Update WP Maps Pro to version 6.1.1 or later.
As a temporary workaround, disable the plugin until the update is applied.
Audit the administrator user list and remove any unrecognized accounts.
Review site logs for POST requests to `wp-admin/admin-ajax.php` with the action `wpgmp temp access support` to identify potential exploitation.
