AI-suggested

A fix is available in Budibase server version 3.45.0. Users should upgrade to version 3.45.0 or later to remediate this vulnerability. No vendor advisory content was provided, but the affectedVersions field and description indicate that versions before 3.45.0 are vulnerable and that upgrading to 3.45.0 addresses the issue.

Description

Budibase server versions prior to 3.45.0 contain a server-side request forgery (SSRF) vulnerability in the Microsoft Teams webhook endpoint. This flaw allows unauthenticated attackers to submit crafted POST requests with attacker-controlled serviceUrl values, which are persisted and used in subsequent bot replies. Exploitation can lead to the server sending live Microsoft OAuth access tokens to attacker-controlled hosts and enable blind internal network access. The vulnerability has a medium severity with a CVSS 4.0 score of 6.3.
