Overview
The cybersecurity community has recently discovered a critical security vulnerability, tagged as CVE-2025-7665, in the Miniorange OTP Verification with Firebase plugin for WordPress. This vulnerability affects versions 3.1.0 to 3.6.2 of the plugin.
The vulnerability is of significant concern as it allows unauthenticated attackers to escalate their privileges and potentially gain administrator access to the system. Systems running the vulnerable versions of the plugin are at risk, making it imperative for users and administrators to take immediate action to mitigate potential threats.

Miniorange OTP Verification with Firebase Plugin for WordPress | 3.1.0 to 3.6.2
How the Exploit Works
The vulnerability lies in the ‘handle_mofirebase_form_options’ function, which lacks a necessary capability check. This omission allows an unauthenticated attacker to send a specific payload to this function, resulting in the default role being updated to Administrator. The attacker can then exploit this elevated access to compromise the system or leak data.
This exploit is particularly dangerous if the premium features of the plugin are enabled as this amplifies the potential damage an attacker can cause.
Conceptual Example Code
The following is a conceptual example of how an attacker might exploit this vulnerability. Note that this is a simplified representation and actual attacks could be more complex.
POST /wp-admin/admin-ajax.php HTTP/1.1
Host: target.example.com
Content-Type: application/x-www-form-urlencoded
action=mo_firebase_auth&form=mo_firebase_settings&mo_firebase_auth_role=adminIn this example, the attacker sends a POST request to the admin-ajax.php endpoint (a common endpoint for WordPress AJAX calls), with the action set to ‘mo_firebase_auth’, the form set to ‘mo_firebase_settings’, and the ‘mo_firebase_auth_role’ set to ‘admin’. This causes the default role to be updated to Administrator, granting the attacker high-level access to the system.
To protect your systems from this vulnerability, it is recommended to apply the vendor’s patch as soon as possible. If immediate patching is not feasible, implementing a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can provide temporary mitigation.
