What is CVE-2026-72849?

Budibase versions prior to 3.40.0 are affected by a cross-site request forgery vulnerability in the chat-link handoff endpoint. This vulnerability enables attackers to exploit a phishing page that can automatically submit a POST request with a stolen confirmation token. By doing so, they can link their external chat identity to a victim's account, leading to unauthorized impersonation and the inheritance of permissions associated with the victim's account during agent operations.
