CVE-2026-72849 [HIGH] – Budibase before 3.40.0 contains a cross-site request forgery vulnerability in the chat-lin

Budibase before 3.40.0 contains a cross-site request forgery vulnerability in the chat-link handoff endpoint that allows attackers to bind an external chat identity to a victim’s account. Attackers can craft a phishing page that auto-submits a POST request with a leaked confirmation token to bind their chat identity to a victim user’s account, enabling impersonation within agent operations and inheritance of victim permissions.
