CVE-2025-14799Public exploitNetwork attack vector

Unauthenticated integration reset via PHP type juggling

Published Feb 18, 2026 · Updated Feb 18, 2026

Authorization bypass in the Brevo WordPress plugin 3.3.0 and earlier allows remote attackers to erase integration settings via a REST request. The mailin_disconnect endpoint accepts public DELETE requests and loosely compares its id parameter with the stored installation ID, so boolean true passes for a nonempty ID. No authentication is required; exploitation disconnects Brevo, deletes its API key and subscription forms, and resets plugin settings.
