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 issue exists due to a flawed 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 security check ineffective. Attackers can invoke the `wpgmp temp access support()` handler by passing the parameter `check temp=false`, which triggers the `wp insert user()` function to unconditionally create a new WordPress user with a hardcoded administrator role. The system then returns a magic login URL that uses `wp set auth cookie()` to fully authenticate the attacker as the new administrator, leading to complete site takeover. Approximately 15,000 sites are estimated to be affected, and active exploitation has been observed, 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 can be 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.
