Prior to 3.39.0, `GET /api/chat-links/:instance/:token/handoff` is a public endpoint (no auth required) that performs a permanent, state-changing operation: it binds an external chat identity (Slack/Discord/MS Teams) to an authenticated Budibase user account, with no consent UI and no CSRF protection. The session token in the URL is created by the attacker (from their own /link slash command) and embeds the attacker's externalUserId. When an authenticated Budibase victim visits the URL, their account is silently and permanently linked to the attacker's Slack/Discord identity. The server responds with \"Authentication succeeded.\" \u2014 no indication of what was linked. This vulnerability is fixed in 3.39.0."}], "source": {"advisory": "GHSA-v7j5-vc4m-723w", "discovery": "UNKNOWN"}}}}
