CVE-2026-50132— Budibase 权限许可和访问控制问题漏洞

Budibase: Chat Identity Link Hijacking via Missing Consent & CSRF — Account Impersonation in Budibase

Budibase is an open-source low-code platform. 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." — no indication of what was linked. This vulnerability is fixed in 3.39.0.

访问控制不恰当

Budibase 权限许可和访问控制问题漏洞

Budibase是英国Budibase公司开源的一个用于在几分钟内创建内部应用程序、工作流和管理面板的低代码平台。 Budibase 3.39.0之前版本存在安全漏洞，该漏洞源于对/api/chat-links/:instance/:token/handoff端点缺乏身份验证、用户同意界面及跨站请求伪造保护，可能导致攻击者将外部聊天身份绑定到已认证用户账户。
