WordPress · Brevo – Email · CVE-2025-14799
**Name of the Vulnerable Software and Affected Versions**
Brevo - Email, SMS, Web Push, Chat, and more. plugin for WordPress versions up to and including 3.3.0
**Description**
The Brevo plugin for WordPress has an authorization bypass issue caused by type juggling. This occurs because of the use of loose comparison (==) instead of strict comparison (===) when validating the installation ID. An unauthenticated attacker can exploit this by sending a boolean `true` value for the `id` parameter to the `/wp-json/mailin/v1/mailin disconnect` API endpoint. Successful exploitation allows attackers to disconnect the Brevo integration, delete the API key, remove all subscription forms, and reset plugin settings. The vulnerable parameter is `id`.
**Recommendations**
Update the Brevo - Email, SMS, Web Push, Chat, and more. plugin for WordPress to a version later than 3.3.0.
