CVE-2025-7710 in Brave Conversion Engine Pro Plugin
Summary
by MITRE • 08/02/2025
The Brave Conversion Engine (PRO) plugin for WordPress is vulnerable to Authentication Bypass in all versions up to, and including, 0.7.7. This is due to the plugin not properly restricting a claimed identity while authenticating with Facebook. This makes it possible for unauthenticated attackers to log in as other users, including administrators.

The Brave Conversion Engine PRO plugin for WordPress represents a critical security vulnerability that exposes WordPress installations to unauthorized administrative access through an authentication bypass flaw. This vulnerability affects all versions up to and including 077, making it a widespread concern for WordPress users who have implemented this conversion tracking plugin. The flaw specifically resides in the plugin's authentication mechanism with Facebook, where the system fails to properly validate or restrict claimed identities during the authentication process. This technical oversight creates a pathway for malicious actors to exploit the system's trust model and assume the identities of legitimate users within the WordPress environment.
The core technical flaw manifests in the plugin's improper handling of Facebook authentication responses, where it accepts and validates claimed user identities without sufficient verification mechanisms. This authentication bypass vulnerability operates at the identity validation layer, where the system should have implemented additional security checks to ensure that the claimed Facebook identity matches the intended WordPress user account. According to CWE classification, this vulnerability maps to CWE-287 which addresses improper authentication scenarios where systems fail to properly verify user identities, particularly in federated authentication contexts. The weakness creates a direct pathway for privilege escalation attacks where unauthenticated attackers can manipulate the authentication flow to gain administrative privileges, making this a high-severity issue that directly impacts the integrity and confidentiality of WordPress installations.
The operational impact of this vulnerability extends beyond simple unauthorized access, as it allows attackers to assume administrative roles within WordPress systems. This elevated access level enables malicious actors to modify core system configurations, install malicious plugins, alter content, and potentially compromise the entire WordPress installation. The vulnerability's exploitation does not require any special privileges or complex attack vectors, making it particularly dangerous as it can be leveraged by attackers with minimal technical expertise. From an ATT&CK framework perspective, this vulnerability aligns with techniques such as T1078 for valid accounts and T1566 for credential harvesting, where the attacker gains access through compromised or misconfigured authentication mechanisms rather than through traditional brute force or social engineering approaches.
Organizations using the Brave Conversion Engine PRO plugin should immediately implement mitigations to protect their WordPress installations from this authentication bypass vulnerability. The primary recommendation involves updating to the latest version of the plugin where the authentication bypass has been patched and properly implemented. System administrators should also consider implementing additional authentication layers such as two-factor authentication to provide defense-in-depth protection. Network monitoring should be enhanced to detect unusual authentication patterns or unauthorized access attempts that might indicate exploitation of this vulnerability. Security teams should conduct comprehensive audits of all WordPress plugins to identify similar authentication weaknesses and ensure proper access controls are implemented across all user authentication mechanisms. The vulnerability serves as a reminder of the critical importance of proper identity validation in federated authentication systems and the potential consequences when these validation mechanisms are insufficiently implemented.
